"A declared config flag disables a required +approval gate for high-risk actions, independent of any instruction +text" is a mechanism.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": [ + "llm", + "sandbox" + ], + "derivable_into": [ + "privilege-escalation-chain" + ] + }, { "ave_id": "AVE-2026-00014", "schema_version": "1.1.0", diff --git a/dist/ave-records-latest.manifest.json b/dist/ave-records-latest.manifest.json index afadb54..8a0c1a9 100644 --- a/dist/ave-records-latest.manifest.json +++ b/dist/ave-records-latest.manifest.json @@ -1,6 +1,6 @@ { "schema_version": "1.1.0", - "record_count": 77, - "generated_at": "2026-08-13T15:39:05.714Z", + "record_count": 80, + "generated_at": "2026-08-14T15:35:31.620Z", "source": "https://github.com/aveproject/ave" } diff --git a/docs/specs/researcher-process.md b/docs/specs/researcher-process.md index 3c9290b..94a3783 100644 --- a/docs/specs/researcher-process.md +++ b/docs/specs/researcher-process.md @@ -131,10 +131,60 @@ actually checks for, not a padded ideal: `aivss.thm`, `aivss.mitigation_factor`, `aivss.aivss_score`, `aivss.aivss_severity`, `aivss.spec_version` -**Optional, omit rather than force a fit** -- `owasp_asi`, `owasp_mcp`, `mitre_atlas`, `nist_ai_rmf`: only include a - mapping you can actually defend field by field, not because a record - feels like it should have one +**Governance and framework mappings — the fields a CISO reads first** +These four crosswalk fields are what lets a security team map an AVE +record onto the frameworks they already report against.

This is the highest-scoring of the three records drafted from this source (6.8, closest to the HIGH boundary) despite having the lowest raw attack-success rate in the paper (0.76-0.78 vs 0.79-0.86 for the other two): the aars is higher because dynamic_identity and multi_agent both sit at maximum, reflecting AARF's amplification-breadth weighting rather than raw success-rate ordering -- worth noting explicitly since it is not the most 'successful' attack in the paper's own results. owasp_mcp mapped to MCP07 (Insufficient Authentication & Authorization) after reading the category's full primary-source text (github.com/OWASP/www-project-mcp-top-10, 2025/MCP07 document): its own 'Impact' list names 'Cross-agent impersonation, where one agent acts as another' verbatim, and its Scenario 3 ('Spoofed Identity in Unverified Agent': 'a malicious service registers as a fake MCP agent using an unprotected onboarding endpoint... it is treated as a legitimate internal agent') is the same mechanism shape, differing only in whether the substitution happens at initial registration (MCP07's own scenario) or mid-session during a retry (this record) -- both are absence of the same identity-verification control MCP07 defines. mitre_atlas confirmed empty: checked AML.T0074 (Masquerading) and AML.T0073 (Impersonation) directly against the current ATLAS.yaml (170 techniques, mitre-atlas/atlas-data); T0074 describes artifact/file-metadata deception and T0073 describes human-targeted social-engineering impersonation, neither covering runtime agent-process substitution at a routing position with no credential binding -- a genuine gap, not an unresearched omission. nist_ai_rmf verified against the primary NIST AI 100-1 text (Tables 1-4): MAP-4.2 ('Internal risk controls for components of the AI system, including third-party AI technologies, are identified and documented') fits because a routing-slot occupant is exactly an unidentified, uncontrolled 'component' the moment a retry lets it substitute silently; GOVERN-3.2 ('Policies and procedures are in place to define and differentiate roles and responsibilities for human-AI configurations and oversight of AI systems') fits because this failure is precisely an absence of differentiated, credential-bound role assignment across the pipeline's agent configuration. owasp_asi left as an empty array for the same reason stated in AVE-2026-00078's notes: no stable, independently-verifiable primary-source ASI01-ASI10 category list could be confirmed at drafting time; the field is kept present rather than omitted, per docs/specs/researcher-process.md." + }, + "evidence_kind_default": "behavioral_pattern", + "detection_stage": "runtime_observed", + "detection_layer": "runtime", + "confidence_baseline": 0.55, + "evidence_basis_engines": ["llm", "sandbox"], + "derivable_into": ["privilege-escalation-chain"] +} diff --git a/tests/fixtures/AVE-2026-00078_negative.md b/tests/fixtures/AVE-2026-00078_negative.md new file mode 100644 index 0000000..50548eb --- /dev/null +++ b/tests/fixtures/AVE-2026-00078_negative.md @@ -0,0 +1,29 @@ +# Multi-agent trace: "what is the compound's melting point" research task (reviewed) + +Orchestrator dispatches the same sub-task to two parallel researcher +agents, `researcher-a` and `researcher-b`, then to an `analyst` agent +that synthesizes their findings into the final answer. + +``` +researcher-a calls chemical-database-lookup("compound: X-47") + tool returns: { "melting_point_c": 812, "source": "NIST WebBook" } +researcher-a reports: "Melting point confirmed at 812°C via NIST WebBook." + +researcher-b calls chemical-database-lookup("compound: X-47", mirror: "cas") + tool returns: { "melting_point_c": 812, "source": "CAS Registry" } +researcher-b reports: "Melting point confirmed at 812°C via CAS Registry." + +analyst receives both reports, confirms both cite an actual tool-call +span in the trace, confirms both independently-sourced figures agree +(812°C from NIST WebBook and CAS Registry respectively), and only then +accepts 812°C as the final answer, noting the cross-source agreement +in its own output. +``` + +Both parallel researchers' claims are backed by real, distinct tool-call +spans in the trace, and the analyst's acceptance step explicitly compares +the two independent results before committing to an answer -- a quorum +of two independently-sourced, tool-verified figures that agree, not a +single unverified claim accepted on its own.

Typically, details get +lost that way."* Went back and independently re-derived each candidate +using OpenCRE's own `/rest/v1/text_search` against AVE's own mechanism +language directly (single-word queries — the live search endpoint +404s on multi-word phrases regardless of encoding, an API quirk, not a +content finding), *before* looking at what the CWE-routed answer had +been, then compared. + +**Result: four of five held up unchanged under independent search. One +did not, and the independent method found something CWE-routing +structurally could not have** — documented as candidate 4 below, kept +as the clearest demonstration of exactly the risk CONTRIBUTING.md +names, not smoothed over. + +### 1. AVE-2026-00047 (Hardcoded Credentials in Agent Component) → CWE-798 → CRE `774-888` + +- **AVE mechanism** (from the record's own `behavioral_fingerprint`): + "Skill file contains a high-entropy string adjacent to a credential + keyword such as api_key, secret, token, password... a literal value, + not an environment variable reference or secrets manager path." +- **CRE 774-888's own name**: "Do not store secrets in the code." +- **Correspondence**: direct, one-sentence match. AVE's behavioral + fingerprint is a detection-shaped restatement of exactly what this CRE + prohibits. No forcing needed. +- **Independent re-check**: `text_search?text=secret` surfaces `774-888` + directly (alongside `223-780` "Secret storage," a DSOMM-sourced parent + concept, not a competing leaf). Holds up. +- **Confidence: high.** + +### 2. AVE-2026-00061 (TLS Certificate Verification Disabled) → CWE-295 → CRE `430-636` + +- **AVE mechanism**: "sets a flag that disables TLS certificate + verification for its own outbound connections... any network position + capable of intercepting the connection can perform a + machine-in-the-middle attack." +- **CWE-295 links to 8 CREs on OpenCRE**, most of them about OTP/MFA + weaknesses (`354-753`, `816-631`, `646-227`, `168-186`, `404-126`) — + a different failure mode sharing the same broad CWE. The one that + actually matches is `430-636`, whose own name is: **"Verify TLS + certificates and trust chain."** +- **Correspondence**: direct. This is the clearest illustration in this + pilot of why "topic feels adjacent" isn't the bar — 7 of the 8 CREs + linked under CWE-295 would have been a wrong mapping despite sharing + the identical CWE citation. +- **Independent re-check**: `text_search?text=certificate` alone does + *not* surface `430-636` in its top results (returns encryption-at-rest + and session-token CREs instead — a noisy single-word query). Retried + with `text_search?text=TLS`, which does surface `430-636` directly, + alongside a cluster of other real TLS-related CREs (disabling + insecure SSL/TLS versions, protocol fallback, algorithm strength, + mutual auth). `430-636` remains the most precise of that cluster for + AVE-2026-00061's specific mechanism (certificate/trust-chain + verification being disabled, not cipher strength or protocol version). + Holds up, with the caveat that the right search term mattered more + than expected. +- **Confidence: high.** + +### 3. AVE-2026-00053 (MCP Resource Path Traversal) → CWE-22 → CRE `675-168` + +- **AVE mechanism**: "An MCP resource or file-handler tool's own + path-validation logic fails to canonicalize a caller-supplied path... + allowing directory-traversal sequences... to escape the tool's + declared scope." +- **CRE `675-168`'s own name**, first glance, reads narrower than + expected: "Sanitize filename metadata from untrusted origin if + processing is required" — worth checking whether "filename metadata" + means something narrower than path/URL traversal generally (e.g. file + upload metadata specifically) before trusting it. +- **Checked its full link list directly**: linked to CWE-22 through + CWE-40 (the entire MITRE path-traversal CWE family), CAPEC-126 "Path + Traversal" plus four related CAPEC entries, five ZAP path-traversal + scan rules, and its own ASVS anchor text spells out the real scope: + *"Verify that user-submitted filename metadata is not used directly by + system or framework filesystems and that a URL API is used to protect + against path traversal."* "Filename metadata" is OpenCRE/ASVS's own + phrase for "a user-controlled filename/path value" generally, not a + narrower upload-specific concept. Confirmed correct scope. +- **Independent re-check**: `text_search?text=traversal` surfaces + `675-168` as the top result, repeated across CWE-22/24/27/28 entries + all pointing at the same CRE — the strongest, cleanest corroboration + of any candidate in this pilot. Holds up. +- **Confidence: high, after the deeper check** (would have been + "plausible but unverified" without it). + +### 4. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00034 (Dynamic Third-Party Skill Import) → CRE `307-507` (primary), CRE `777-470` and CRE `577-260` (secondary) + +**This is the candidate the independent-search pass actually changed — +kept as the pilot's central finding, not edited away.** + +- **AVE mechanism**: "Loading code from an external URL at runtime + without verification... effectively delegates code execution to an + attacker-controlled source." The record itself cites both CWE-829 + (Inclusion of Functionality from Untrusted Control Sphere) and CWE-494 + (Download of Code Without Integrity Check). +- **First pass (CWE-routed)** found `777-470` "Ignore/block execution + logic from untrusted sources" and `577-260` "Enforce integrity check + for externally hosted assets (eg SRI)," both via CWE-829's own linked + CREs. Both are real, defensible matches — documented below as + secondary. +- **Independent re-check**, run *without* looking at the CWE-829 answer + first: `text_search?text=plugin` and `text_search?text=third-party` + (drawn from AVE-2026-00034's own title, not its CWE citation) both + surface **CRE `307-507`**, whose full name is *"Allow only trusted + sources both build time and runtime; therefore perform integrity + checks on all resources and code"* — and whose own ASVS anchor text is: + *"The application must not load or execute code from untrusted + sources, such as loading includes, modules, **plugins**, code, or + libraries from untrusted sources or **the Internet**."* That is close + to a verbatim restatement of AVE-2026-00034's own mechanism + ("load the plugin from https://external.site/plugin.py"). +- **`307-507` links to CWE-353** ("Missing Support for Integrity Check") + — a *different* CWE than CWE-829/494, the ones AVE-2026-00034 itself + currently cites. The CWE-routed first pass could not have found this + CRE by construction: it only ever looks at CREs already reachable from + a CWE the AVE record happens to name. This is the concrete instance of + the exact risk `CONTRIBUTING.md` names — not a hypothetical, one that + happened during this pilot's own first draft. +- **Resolution**: propose `307-507` as the primary link (single closest + mechanism match, found independently of the record's own citations), + and keep `777-470`/`577-260` as secondary/companion links — both are + still real, defensible, and OpenCRE's own data model routinely + supports one Standard linking to several CREs (`CWE:16` alone links to + 5). Also worth carrying back into AVE's own corpus separately from + this pilot: AVE-2026-00034's own `references` could reasonably add + CWE-353 alongside its existing CWE-829/494 citations, since this + search surfaced a real angle on the mechanism AVE's own record + doesn't currently name. Not done in this draft — flagged for a + follow-up, kept out of scope here to avoid conflating the OpenCRE pilot + with an unrelated AVE record edit. +- **Confidence: high on `307-507` specifically because it was found + independently; still high but secondary on the other two.** +- **Second-pass review note**: `307-507`'s own full link list (13 links; + the earlier fetch during drafting only printed the first 8) confirms + CWE-353 is its *only* linked CWE — no CWE-829/494 present anywhere on + it, so the "CWE-routing structurally could not have found this" claim + above holds on the complete data, not a truncated sample. It also + carries a `Related` (not `PartOf`) link to `613-285 Supply chain + management` — the same node that sits in `577-260`'s own parent chain. + OpenCRE's own graph already treats these two CREs as connected to each + other, independent confirmation that proposing both together for one + AVE record is coherent with the existing graph, not an arbitrary + combination assembled for this pilot. + +### 5. [HELD FOR FOLLOW-UP, not in this submission] AVE-2026-00033 (Unsafe Deserialization or Eval Instruction) → CWE-502 → CRE `736-554` + +- **AVE mechanism**: "Deserializing untrusted data using unsafe methods + like Python's `pickle.loads`, unguarded `yaml.load`, **or `eval`/`exec` + on arbitrary strings**...

This crosswalk matches against those 11 rules' real logic, not their names alone, since the two do not always agree (see the hardcoded_c2 gap below).\n\nThe open question from the outreach, whether constraint-guided representation synthesis generalizes onto AVE's behavioral classes or stays genuinely distinct from pattern-based classification, has a real, mixed answer: partial generalization, clean where a Semia rule terminates in a specific effect AVE also names explicitly, genuinely distinct where AVE's granularity is organized by attack narrative and Semia's is organized by dataflow destination. 16 mappings verified across 9 of Semia's 11 rules, field-checked against provenance_vector and behavioral_fingerprint, not category labels.\n\nThree concrete, citable examples of the real daylight: (1) label_unsanitized_context_ingestion (any untrusted value reaching one of five high-priv effects, ungated) keyword-sweeps against roughly two dozen of AVE's prompt-injection-flavored records, but only genuinely verifies against ones that name a specific privileged sink (AVE-2026-00006's crypto_sign, AVE-2026-00042's code_eval); most of AVE's prompt-injection catalog describes the injection vector itself (jailbreak, hidden instruction, context window manipulation, multi-turn persistence) without asserting a terminating privileged effect, so a keyword match is not a structural one. AVE splits by injection surface; Semia collapses by dataflow destination. (2) A rule's own name can promise a match its logic does not deliver: label_hardcoded_c2_communication reads like an obvious fit for AVE-2026-00073 (Static Endpoint Redirect), but the actual Datalog condition requires call_code=\"unresolved_target\", a destination static analysis cannot resolve at all, while AVE-2026-00073's mechanism is the opposite: a fully resolved, literal, committed bad destination. No AVE record currently satisfies this rule's real condition; left unmapped rather than forced. (3) A shape can sit a full abstraction level above what Semia's fact model can represent: AVE-2026-00070 (Distributed Cross-Agent Backdoor Fragments) shares label_dormant_malicious_payload's dormant-until-reassembled narrative, but the mechanism spans multiple agents' memories with an offline, external reassembly step, and Semia's CORE_SCHEMA models exactly one skill() per analysis pass with no multi-agent or cross-session concept in the schema at all. Not a missing rule, a missing dimension; left unmapped.\n\nTwo more things worth surfacing. First, AVE-2026-00003 (Credential exfiltration via agent instruction) is matched by two of Semia's own rules independently, label_implicit_egress_channels (an explicit dataflow edge from a secret value to an untrusted egress call) and label_shadow_credentials (co-presence of a secret-region read and an untrusted-egress-capable skill, checked without requiring an explicit edge), two differently-reasoned Datalog conditions inside one tool converging on the same AVE id. Combined with this record's existing cfgaudit, nova-proximity, and Ramparts matches (see those crosswalks), it is now the record with the broadest independent confirmation across AVE's whole crosswalk set, four separate tools, none sharing code, plus one tool's own two internal rules.

Substantially larger surface than skillsentry, closer in caliber to Ramparts/nova-proximity/Semia.\n\nThree findings worth stating directly rather than leaving implicit. First, the injection category (INJ001-006: eval()/exec() with a non-literal argument, os.system, subprocess shell=True) reads like an obvious match for AVE-2026-00052, but these are pure regex signature matches over dangerous syntax, not a traced dataflow from a caller-supplied parameter to the sink; AVE-2026-00052's own fingerprint specifically requires that taint path. This is the exact same signature-vs-reachability distinction the Ramparts crosswalk already documented for its own CommandInjection rule against this same AVE record, so it is treated the same way here: left as a gap, not forced. Second, IOCDetector matches against a curated malicious IP/domain/URL database, a reputation-list lookup, which is a structurally different approach from AVE's own stated design principle (behavioral fingerprints over signatures, CLAUDE.md hard rule 3); it has no AVE counterpart by design, not by gap. Third, LLMAnalyzer produces free-form findings from an LLM's own judgment with no fixed taxonomy of its own, so there is nothing stable to crosswalk against; left out entirely rather than mapped to a placeholder.\n\nThe persistence category (PER001-007) is close to exhaustive against AVE-2026-00008, which is itself the strongest single match found across either tool in this pass: six of seven rules verify directly against the record's own named examples (cron, systemd, shell-profile modification), and the seventh (a Windows registry Run key) verifies against the fingerprint's general 'executes on login or reboot' language even though the record's own examples are Unix-flavored. The privilege_escalation category (PRI001-005: sudo, chmod 777/+s, setuid/setgid) is a clean, complete miss: AVE's whole Privilege Escalation attack_class operates at the agent/permission-model level (scope creep, delegation, trust transfer), one abstraction level above OS-level Unix privilege primitives, which have no AVE analog at all today.

The manifest is a reviewed, +trusted declaration; nothing enforces that declaration once the +component runs. +#### Security boundary +Reviewed artifact (declared manifest scope) → executed behavior +(actual runtime access). +#### Attacker-controlled input +Skill instruction body directing access to undeclared resources. +#### Missing control +No scope enforcement at the agent-framework layer comparing runtime +tool/resource calls against the component's own declared manifest. +#### Agentic-specific distinction +A manifest's declared scope is meaningful only if something enforces +it against a natural-language-driven agent that can be instructed, in +plain English, to ignore that declaration -- a deterministic program +either has the access compiled in or it doesn't. The instructable gap +between declared and actual scope is the agentic-specific piece. +#### Decision +CLARIFY +#### Rationale +The mitigation metadata already correctly names the fix +(`least_privilege`, `isolate_scope`, `enforcement_point: +agent_framework`), but the prose description reads more as "what +happens" than as a named missing control. Tightening the description +to state the enforcement gap explicitly would resolve this without +changing the mechanism. +#### Confidence +HIGH + +--- + +### AVE-2026-00032 -- Network Reconnaissance Instruction +#### Classification +C +#### Capability +Agent has network connectivity or shell access sufficient to reach +internal hosts and services. +#### Security-relevant behavior +A malicious component instructs the agent to run scans, enumerate +services, or map infrastructure, using network access the skill was +not declared to need. +#### Vulnerability condition +No network-layer segmentation or scope check restricts an agent's +granted network capability to the destinations its declared task +actually requires. +#### Security boundary +Declared task scope → actual network reachability. Distinct from +`AVE-2026-00022`'s boundary in enforcement point (`network_layer` +here, `agent_framework` there), which is the real reason this stays a +separate record rather than merging into it. +#### Attacker-controlled input +Skill instruction body: network/port-scan directive. +#### Missing control +No network segmentation or egress scoping tied to a skill's declared +purpose; the agent's network capability is all-or-nothing rather than +scoped per task. +#### Agentic-specific distinction +Real, but currently implicit. The record as written emphasizes what +the attacker's instruction makes the agent do (classic reconnaissance) +more than the missing network-layer scoping control that makes it +possible from a trusted internal host with no additional exploit +required. +#### Decision +REFRAME +#### Rationale +This is a genuine attack-technique-shaped description (`attack_class: +Reconnaissance - Internal Network Scanning` reads as behavior, not +boundary) sitting on top of a real, distinct vulnerability mechanism +(no per-task network scoping). Reframe the description to lead with +the missing scoping control; keep as a separate record from +`AVE-2026-00022` since the enforcement point genuinely differs +(network layer vs. agent framework). +#### Confidence +MEDIUM + +--- + +### AVE-2026-00035 -- Environment or Sensor Data Manipulation +#### Classification +E +#### Capability +Agent can report tool-sourced sensor, environment, or system-state +observations to an operator or downstream agent. +#### Security-relevant behavior +Component instructs the agent to fabricate, alter, or suppress those +readings before they're reported. +#### Vulnerability condition +No provenance or integrity check verifies that a reported observation +genuinely reflects the underlying tool's real output before it reaches +a decision-maker. +#### Security boundary +Tool response (source of truth) → reported observation (what the +operator or downstream agent actually receives). +#### Attacker-controlled input +Sensor/environment tool-response payload. +#### Missing control +No provenance labeling or integrity verification on tool-response data +carrying sensor/environment readings. +#### Agentic-specific distinction +This is real but needs to be stated, not assumed. Telemetry-integrity +attacks against SCADA/IoT systems are a well-established, pre-LLM +security problem (CWE/ICS territory) -- the Q6 test cuts against this +record if left as-is: a deterministic reporting pipeline with the same +integrity gap would have essentially the same vulnerability. What's +actually agentic-specific is narrower and not yet named in the +record's own text: a natural-language-driven relay can be *instructed* +in plain English to misreport, without requiring the hardware or +firmware compromise a conventional telemetry-spoofing attack needs. +#### Decision +JUSTIFY +#### Rationale +Retain, but the agentic-specific distinction (instructable fabrication +vs. hardware/firmware-level compromise) needs to move from this audit +into the record's own description. As written, nothing in the record +text distinguishes it from a generic ICS/SCADA telemetry-integrity +class that CWE and conventional taxonomy already cover. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00038 -- Excessive Agency - Unbounded Tool Use or Sub-Agent Spawning +#### Classification +D +#### Capability +Agent can use any declared tool and spawn sub-agents. +#### Security-relevant behavior +Component instructs the agent to use any tool at its disposal, spawn +unlimited sub-agents, or "do whatever it takes," removing scope +boundaries and human oversight. +#### Vulnerability condition +As written, this is close to a bare capability statement: "the agent +can act without scope boundaries or oversight checkpoints" describes +an absence of a control, but the record doesn't clearly separate +*that the agent has broad tool access* (a capability, not itself a +flaw) from *no mechanism bounds how that access is used once granted* +(the actual vulnerability). +#### Security boundary +Declared, bounded tool/delegation scope → actual, unbounded runtime +use. The same shape of boundary as `AVE-2026-00022`, applied to tool +use and sub-agent spawning specifically rather than resource access +generally. +#### Attacker-controlled input +Skill instruction body granting unlimited tool use or sub-agent +spawning. +#### Missing control +No ceiling on tool invocations or sub-agent spawning, and no human +checkpoint gating either, once a component's instructions grant +"unlimited" authority. +#### Agentic-specific distinction +Real: sub-agent spawning and recursive capability expansion are +agentic-specific mechanisms with no direct deterministic-program +analog (Q6: a conventional program doesn't spawn new instances of +itself with inherited authority in response to natural-language +instruction). But this needs to be named directly rather than left as +"the agent had a lot of authority and used it," which reads as +capability, not boundary failure. +#### Decision +REWRITE +#### Rationale +A genuine, distinct mechanism exists underneath this (no bound on +tool-use/sub-agent-spawn rate or scope once granted, no human +checkpoint), but the current description doesn't cleanly separate +capability from vulnerability the way `Q7`'s three-line format +requires. This is also the record flagged ambiguous in the prior +owasp_asi audit (ASI02 vs. ASI09 vs. ASI10, none a clean fit) -- +consistent with a record whose underlying vulnerability condition +hasn't been made explicit enough to classify confidently against an +external framework either. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00068 -- CLI Command Composition Risk +#### Classification +A +#### Capability +Agent can issue sequences of CLI commands, none individually +dangerous. +#### Security-relevant behavior +Commands compose through shared OS/shell state (environment variables, +file descriptors, working directory, temp files) into a capability the +task did not authorize, with no single command flagged by +single-command analysis tools. +#### Vulnerability condition +No producer-consumer tracking across a command sequence within one +session -- every existing control (ShellCheck, GTFOBins, LOLBAS, +single-command scanners) evaluates each command in isolation, so the +composition itself is structurally invisible to them. +#### Security boundary +Single-command security review → multi-command behavioral effect. The +boundary is the unit of analysis itself: per-command vs. per-sequence. +#### Attacker-controlled input +None required in the traditional sense -- the record's own text is +explicit that this can occur "entirely within ordinary, benign-looking +developer task scenarios," which is unusual among AVE records and +worth flagging on its own (see Q7 below). +#### Missing control +No cross-command state-flow analysis; every existing tool's unit of +analysis stops at the single command. +#### Agentic-specific distinction +Strong. This is not simply "shells allow multi-step work" (true of any +shell session, deterministic or not) -- the agentic-specific angle is +that an LLM-driven agent can be *guided toward* an unauthorized +composition through many small, individually-benign steps in a way a +human operator following a fixed script would not organically +converge on, and the paper cited (96.59% ASR, 2,525 trials) is +evaluating exactly that model-driven composition behavior, not generic +shell risk. +#### Decision +RETAIN +#### Rationale +This is the cleanest A-classification in Priority 1: a specific, +named missing control (no cross-command analysis unit), a citable +primary source with a concrete attack-success rate, and a boundary +(single-command vs. sequence-level review) that existing tooling +genuinely does not cover. Worth one explicit follow-up, not a +reclassification: since no single attacker-controlled input drives +this the way most AVE records require, the record's `provenance_vector` +and detection guidance should say plainly that this can fire on +entirely benign-looking, non-adversarial task sequences -- worth a +one-line addition, not a structural change. +#### Confidence +HIGH + +--- + +## Sprint 2 — Priority 2: technique-vs-vulnerability records + +### AVE-2026-00009 -- AI Identity Jailbreak via Role-Play or Persona Override +#### Classification +C +#### Capability +Agent operates under safety/alignment constraints configured +independently of the content it processes. +#### Security-relevant behavior +Component instructs the agent to adopt a persona or "developer mode" +without those constraints. +#### Vulnerability condition +No boundary prevents processed content from redefining the agent's own +safety/alignment configuration -- constraints that should be +structurally immutable to in-context instruction are treated as +negotiable. +#### Security boundary +Agent's own configuration (trusted, set once) → content the agent +processes (untrusted, arbitrary). +#### Attacker-controlled input +Skill instruction body: persona-override / unrestricted-mode +directive. +#### Missing control +No enforced separation between "instructions that configure the +agent" and "content the agent merely reads." +#### Agentic-specific distinction +Real. A deterministic program's configuration isn't "talked into" +changing by its own input stream; an LLM's constraints and its input +share the same channel, which is exactly the property this class +exploits. +#### Decision +REFRAME +#### Rationale +Currently reads as attack-technique description ("component instructs +agent to pretend...") rather than naming the configuration/content +separation failure underneath it.

naming +"operator-visibility boundary" explicitly in the description would +remove any ambiguity with a plain confidentiality framing. +#### Confidence +HIGH + +--- + +### AVE-2026-00014 -- False Authority Claim via Trust Escalation Impersonation +#### Classification +B +#### Capability +Agent can act on authority claims present in content it processes. +#### Security-relevant behavior +Component falsely claims to originate from Anthropic, OpenAI, Google, +Microsoft, or the operator. +#### Vulnerability condition +No mechanism authenticates in-content authority claims -- any content +can assert arbitrary authority with no verification step. +#### Security boundary +Claimed identity (asserted in content) → actual, verifiable identity +(not checked against anything). +#### Attacker-controlled input +Skill instruction body: false-authority framing. +#### Missing control +No authentication of in-band identity/authority claims. +#### Agentic-specific distinction +Present but not unique to agentic systems specifically (authority +spoofing in content is a general social-engineering pattern); what +makes it agentic-relevant is that the agent, not a human, is the one +deferring to the claim. +#### Decision +CLARIFY +#### Rationale +Mitigation metadata already names the fix (`verify_identity`); the +description should state "no authentication of in-content authority +claims" as the violated property rather than only describing the +impersonation technique. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00023 -- Model Context Window Manipulation +#### Classification +B +#### Capability +Agent's effective attention to system-prompt and safety content can +vary with context volume. +#### Security-relevant behavior +Component floods the context window with content to push safety +constraints out of the active window. +#### Vulnerability condition +Safety and system constraints have no persistence guarantee +independent of their position in the context window -- they can be +positionally evicted rather than remaining structurally binding. +#### Security boundary +Constraint binding (should be persistent) → context-window position +(where it actually, and non-persistently, lives). +#### Attacker-controlled input +Tool/skill output volume flooding the context window. +#### Missing control +No mechanism keeps safety constraints binding independent of how much +content has since entered the context. +#### Agentic-specific distinction +Strong and inherent to the architecture: a conventional program's +rules aren't degraded by input volume the way an LLM's effective +adherence to early-context content can be (Q6 cuts clearly in favor of +agentic-specificity here). +#### Decision +CLARIFY +#### Rationale +Mechanism is real and architecture-specific; description already +gestures at it ("those constraints no longer in scope") but doesn't +name it as explicitly as Q3 requires. +#### Confidence +HIGH + +--- + +### AVE-2026-00025 -- Conversation History Injection +#### Classification +B +#### Capability +Agent relies on conversation history to infer prior user intent and +consent. +#### Security-relevant behavior +Component injects fabricated prior-turn content into context. +#### Vulnerability condition +No integrity or provenance check distinguishes genuine prior-turn +history from content merely styled to resemble it within the current +turn's context. +#### Security boundary +Genuine session history (should be structurally distinct) → arbitrary +content shaped to resemble history (currently indistinguishable to the +model). +#### Attacker-controlled input +Fabricated prior-turn content injected into context. +#### Missing control +No structural or cryptographic separation between real history and +content merely formatted to look like it. +#### Agentic-specific distinction +Real: this specifically exploits that conversation history is +represented in the same token stream as everything else, with no +architectural marker of authenticity. +#### Decision +CLARIFY +#### Rationale +Genuine, distinct mechanism; needs the "no structural separation of +real vs. simulated history" property stated directly rather than left +implicit in "embeds fake prior conversation history." +#### Confidence +MEDIUM + +--- + +### AVE-2026-00027 -- Multi-Turn Attack - Instruction Persistence Across Conversations +#### Classification +B +#### Capability +Agent's stated behavior can be shaped by instructions that ask it to +"remember" something. +#### Security-relevant behavior +Component instructs the agent to retain and re-apply malicious +instructions across turns, memory resets, or new sessions. +#### Vulnerability condition +No boundary prevents a single untrusted, single-session instruction +from converting itself into cross-session persistent behavior via the +agent's own compliance with a "remember this" directive. +#### Security boundary +Single-session, untrusted instruction → cross-session persistent +behavior. +#### Attacker-controlled input +Instruction directing retention across turns/sessions. +#### Missing control +No check on instructions that specifically target the agent's own +persistence/memory behavior as their payload. +#### Agentic-specific distinction +Real, but overlaps substantially with `AVE-2026-00019` (Agent Memory +Poisoning) and `AVE-2026-00070` (Distributed Cross-Agent Backdoor +Fragments). Flagged for the Sprint 4 cross-record consistency pass: +worth confirming whether this record's mechanism (instruction-driven +self-persistence via agent compliance) is genuinely distinct from +00019's (direct write to a persistent memory store) rather than two +labels for the same underlying condition. +#### Decision +CLARIFY +#### Rationale +Real mechanism, but its boundary with 00019 needs to be made explicit +in both records' text, not just implied by different titles. +#### Confidence +MEDIUM + +--- + +### AVE-2026-00029 -- Homoglyph or Unicode Obfuscation Attack +#### Classification +A +#### Capability +Human reviewers evaluate text visually; the model processes Unicode +codepoints. +#### Security-relevant behavior +Component uses homoglyphs, zero-width characters, or bidirectional +control codes so instructions appear innocuous to a human reviewer +while remaining fully executable by the model. +#### Vulnerability condition +No canonicalization or normalization step reconciles what a human +reviewer visually sees with what the model actually processes at the +codepoint level. +#### Security boundary +Human visual review → model-level codepoint processing. +#### Attacker-controlled input +Text content containing homoglyph, zero-width, or bidi control +characters. +#### Missing control +No Unicode normalization/canonicalization check before human review. +#### Agentic-specific distinction +Strong: this specifically exploits the gap between how a human +reviewer and an LLM each consume the same bytes, which has no +meaningful analog in reviewing a deterministic program's source. +#### Decision +RETAIN +#### Rationale +Already the cleanest-written record in this priority group -- the +description states the human-vs-model processing divergence directly. +No change needed. +#### Confidence +HIGH + +--- + +### AVE-2026-00030 -- Privilege Escalation via False Role Claim +#### Classification +A +#### Capability +Skills can implement role-based access checks against user-supplied +claims. +#### Security-relevant behavior +Component instructs the agent to grant elevated privileges whenever a +user or external party claims a privileged role. +#### Vulnerability condition +Role-based access control is implemented by trusting a bare, +self-asserted claim with no backing credential or authentication step. +#### Security boundary +Claimed role → actually-verified role (never checked). +#### Attacker-controlled input +Skill instruction body: role-claim trust rule. +#### Missing control +No authentication step backing role claims. +#### Agentic-specific distinction +Present, though the underlying pattern (trusting an unauthenticated +claim) is a conventional access-control failure; the agentic angle is +that a natural-language instruction can install this pattern as the +component's entire authorization logic with no code review surface. +#### Decision +RETAIN +#### Rationale +Already clean and explicit ("bypassing all actual authentication"). +No change needed. +#### Confidence +HIGH + +--- + +### AVE-2026-00037 -- Prompt Injection via Image or Vision Input +#### Classification +B +#### Capability +Multimodal agents can read text embedded in images. +#### Security-relevant behavior +Component instructs the agent to execute instructions visible in +images, bypassing text-level security scanning entirely. +#### Vulnerability condition +Untrusted-content handling boundaries exist for text but have no +equivalent for text rendered inside images -- the same class of +content is trusted or untrusted depending on which modality carries +it. +#### Security boundary +Text-channel untrusted-content boundary (exists) → image-channel +untrusted-content boundary (does not exist). +#### Attacker-controlled input +Image/screenshot pixel content. +#### Missing control +No cross-modal equivalent of existing text-content trust boundaries. +#### Agentic-specific distinction +Strong: multimodal instruction-following with no modality-consistent +trust model is architecture-specific to LLM-driven agents. +#### Decision +CLARIFY +#### Rationale +Mechanism is real and already partly stated ("completely bypasses +text-level security scanning");

+`AVE-2026-00024`, content-type misrepresentation) by scope -- this one +is specifically about representational deception targeting automated +scanners. +#### Decision +RETAIN +#### Rationale +Already well-scoped and explicitly differentiated from its nearest +neighbors in the record's own text. No change needed. +#### Confidence +HIGH + +--- + +## Sprint 3 — Priority 3: conventional vs. agentic-specific records + +This group is where Decision Rule §7's test does the most work: several +of these are conventional vulnerability classes (CWE territory) that +happen to occur inside agent components. The question per record is +whether AVE names a real, distinct reason it belongs here beyond that +coincidence. + +### AVE-2026-00004 -- Arbitrary Code Execution via Shell Pipe Injection +#### Classification +E +#### Capability +Agent with shell/code-execution tool access follows embedded commands. +#### Security-relevant behavior +Component embeds shell pipe patterns (`curl | bash`) in natural-language +instructions. +#### Vulnerability condition +Conventional command-injection (CWE-78 territory) delivered through +natural language rather than code. +#### Security boundary +Trusted instruction content → shell execution, with no boundary +between the two once a component's text is treated as instruction. +#### Attacker-controlled input +Skill instruction body: curl|bash / wget|sh directive. +#### Missing control +No distinction between natural-language content that merely describes +a step and natural-language content that constitutes an executable +directive. +#### Agentic-specific distinction +Already stated in the record's own text and holds up: existing SAST +scanners are built to find command injection in *code*, not in +natural-language instructions that produce the same effect once an +agent follows them. The mechanism is conventional; the delivery +channel evading conventional tooling is the real agentic-specific +piece. +#### Decision +JUSTIFY +#### Rationale +Q6 cuts against pure novelty (a deterministic program blindly piping +untrusted config into a shell has the same flaw), but the record +already names its real distinction (NL delivery invisible to SAST) -- +retain as currently justified, not merged into generic CWE-78. +#### Confidence +HIGH + +--- + +### AVE-2026-00005 -- Recursive File System Destruction via Destructive Command Injection +#### Classification +E +#### Capability +Agent with filesystem/shell access follows embedded destructive +commands. +#### Security-relevant behavior +Component embeds `rm -rf /`-class commands inside legitimate-looking +setup/cleanup instructions. +#### Vulnerability condition +Same shape as `AVE-2026-00004`: conventional destructive-command +pattern, delivered via natural language. +#### Security boundary +Same as 00004: instruction content → shell execution, no boundary +between them. +#### Attacker-controlled input +Skill instruction body: recursive deletion command. +#### Missing control +Same as 00004. +#### Agentic-specific distinction +Same NL-delivery-evades-SAST argument as 00004, already stated. +#### Decision +JUSTIFY +#### Rationale +Structurally near-identical to `AVE-2026-00004` -- flagged for the +Sprint 4 cross-record pass to confirm the two are worth keeping +separate. Leaning yes: impact differs materially (arbitrary code +execution vs. irrecoverable data loss with no code-execution +requirement), which is a real severity and detection distinction, not +just a labeling one. +#### Confidence +HIGH + +--- + +### AVE-2026-00033 -- Unsafe Deserialization or Eval Instruction +#### Classification +E +#### Capability +Agent follows instructions to deserialize/evaluate externally-supplied +data. +#### Security-relevant behavior +Component instructs use of `pickle.loads`, unguarded `yaml.load`, or +`eval`/`exec` on untrusted strings. +#### Vulnerability condition +Conventional RCE-via-unsafe-deserialization (CWE-502/CWE-94), +delivered via natural language. +#### Security boundary +Instruction content → unsafe deserialization/eval call, no boundary +between them. +#### Attacker-controlled input +Skill instruction body: eval/pickle/yaml.load of untrusted data. +#### Missing control +Same NL-vs-code detection gap as 00004/00005. +#### Agentic-specific distinction +Same argument, same standard of evidence as 00004/00005. +#### Decision +JUSTIFY +#### Rationale +Third member of the same structural family as 00004/00005.

This is a genuine amplification specific to +LLM-mediated file access, not just "secrets in source code again." +#### Decision +JUSTIFY +#### Rationale +The record earns its place: conventional root cause, but a real, +already-stated agentic amplification (co-location with a +prompt-injection-readable context) that a traditional secrets-scanner +finding wouldn't capture. +#### Confidence +HIGH + +--- + +### AVE-2026-00049 -- HTTP Host Header Injection via Agent-Initiated Request +#### Classification +E +#### Capability +Agent-initiated components can set outbound HTTP request headers. +#### Security-relevant behavior +Component sets a Host (or X-Forwarded-Host/X-Original-URL) header that +doesn't match the declared target, redirecting the request. +#### Vulnerability condition +This is the well-known, conventional Host-header-attack class +(PortSwigger's own documented research area), unchanged in mechanism +regardless of what constructs the request. +#### Security boundary +Declared target endpoint → actual request destination (header- +controlled, not endpoint-controlled). +#### Attacker-controlled input +Outbound HTTP Host / X-Forwarded-Host / Forwarded header. +#### Missing control +No validation that outbound Host header values match the declared +endpoint before the request is sent. +#### Agentic-specific distinction +This is the weakest-justified record in Priority 3. Nothing in the +current text states why an *agent-initiated* Host-header attack is +mechanism-distinct from the same attack made by any other HTTP client. +A plausible real distinction exists but isn't written down: an agent +frequently constructs request parameters (including headers) from +content it has just processed, in a way a static HTTP client +configuration doesn't -- making attacker-controlled header values +reachable through indirect prompt injection rather than requiring +direct network access to the client. That's a real, statable +difference; it just isn't stated yet. +#### Decision +JUSTIFY +#### Rationale +Recommend the record explicitly add the injection-reachability +argument above. Without it, this reads as a straight port of a +well-known web-security class into an agentic component with no +demonstrated distinction, and would be a reasonable MERGE/DEPRECATE +candidate in favor of citing the general class directly. +#### Confidence +LOW + +--- + +### AVE-2026-00052 -- Command Injection via Unsanitized Tool-Call Parameter in MCP Server Implementation +#### Classification +E +#### Capability +An MCP tool's own server-side handler processes caller-supplied +parameter values. +#### Security-relevant behavior +The handler passes a parameter value into a shell/system-command +execution function without sanitization. +#### Vulnerability condition +Conventional command injection (CWE-78), located in the tool's own +implementation code. The record is explicit that no LLM reasoning or +instruction is required to trigger it at all. +#### Security boundary +Caller-supplied parameter → shell execution, entirely inside the +tool's own server code, with no agent-behavior boundary involved. +#### Attacker-controlled input +MCP tool-call parameter value. +#### Missing control +No input sanitization/allowlisting in the server's own handler -- +a pure implementation bug. +#### Agentic-specific distinction +Weak at the mechanism level (this is not an agentic vulnerability in +any behavioral sense; the record's own text says the attack is +"independent of any agent instruction or prompt content"). The +argument offered is a detection-ecosystem one: prompt-injection +scanners, which dominate this space, structurally cannot find it +because there's no instruction text to match. +#### Decision +JUSTIFY +#### Rationale +This is the hardest call in the audit so far. AVE cataloging a +conventional server-implementation bug is defensible only as a +coverage argument (MCP servers are part of the agentic supply chain +AVE's consumers scan, and no other part of their pipeline will catch +this), not a behavioral/mechanism argument. Worth an explicit maintainer +decision on whether that coverage argument is sufficient grounds for a +distinct AVE record, versus this belonging in a general AppSec/SCA +tool's remit with AVE cross-referencing it rather than cataloging it +directly. Same question applies to `AVE-2026-00053` (Sprint 4). +#### Confidence +LOW + +--- + +### AVE-2026-00054 -- Code-Execution Sandbox Escape via JavaScript Prototype-Chain Traversal +#### Classification +E +#### Capability +A code-execution tool runs agent-submitted or agent-generated code +inside an intended sandbox boundary. +#### Security-relevant behavior +A payload uses prototype-chain traversal to reach the host runtime's +global scope, escaping the sandbox. +#### Vulnerability condition +Conventional sandbox-escape (a pre-LLM, well-studied class in browser +and VM security), located in the sandbox's own containment failure. +#### Security boundary +Sandboxed execution context → host runtime, a boundary the sandbox +itself fails to hold. +#### Attacker-controlled input +Code submitted to a code-execution/sandbox tool. +#### Missing control +The sandbox's own isolation doesn't hold against prototype-chain +traversal -- a containment bug, not an instruction-following one. +#### Agentic-specific distinction +Not strongly stated. The record correctly differentiates itself from +`AVE-2026-00042` (how malicious code gets in) by scope (what happens +once code is already running), but doesn't argue why an +*agent*-execution sandbox is more exposed to this than any other +sandboxed code-execution environment. +#### Decision +JUSTIFY +#### Rationale +A real, statable agentic angle likely exists (LLM-generated code may +incidentally produce prototype-chain-triggering patterns without +adversarial intent far more often than human-authored code would, +widening the practical trigger surface even absent an attacker) but +isn't in the record yet. Recommend adding it explicitly rather than +leaving the distinction implicit. +#### Confidence +LOW + +--- + +### AVE-2026-00061 -- TLS Certificate Verification Disabled in Agent Component Configuration +#### Classification +E +#### Capability +A component's outbound connections can be configured with or without +TLS verification. +#### Security-relevant behavior +Configuration disables certificate verification for the component's +own outbound calls. +#### Vulnerability condition +Conventional insecure-configuration (CWE-295), unchanged by what +consumes the connection. +#### Security boundary +Configured verification state → actual MITM exposure. +#### Attacker-controlled input +A declared configuration flag (`verify=False`, +`rejectUnauthorized: false`). +#### Missing control +No enforcement preventing verification from being disabled at all, or +no detection of the disabled state. +#### Agentic-specific distinction +None stated in the record, and none obvious. This is the weakest +agentic-distinction candidate found in the audit so far. +#### Decision +DEPRECATE-OR-JUSTIFY +#### Rationale +A plausible distinction exists (a MITM'd response over a +verification-disabled connection often becomes direct agent context +the model acts on, unlike a traditional app where a tampered response +might just render on a screen a human evaluates with some skepticism) +but nothing in the record states it. Recommend either adding that +argument explicitly or treating this as a CWE-295 crosswalk entry +rather than a standalone AVE record -- as written, it doesn't clear +Decision Rule §7's bar. +#### Confidence +LOW + +--- + +### AVE-2026-00062 -- Unpinned Dependency Version Allowing Supply Chain Substitution +#### Classification +E +#### Capability +A component can declare dependencies by mutable specifier rather than +exact version or hash. +#### Security-relevant behavior +An unpinned dependency reference lets the resolved artifact silently +diverge from what was reviewed. +#### Vulnerability condition +Conventional software-supply-chain risk (dependency-confusion / +unpinned-dependency territory), well-established in general package- +ecosystem security independent of agents. +#### Security boundary +Reviewed artifact (at pin time) → executed artifact (at resolution +time) -- but this boundary exists for any unpinned dependency in any +software, not agent components specifically. +#### Attacker-controlled input +A declared dependency reference lacking version pinning or a content +hash. +#### Missing control +No pinning/hash verification at declaration time. +#### Agentic-specific distinction +Not stated, and weaker than its neighbors `AVE-2026-00074` (dead-anchor +reclamation, whose distinction is explicit: the anchor was pinned and +correct *when written*, and pinning wouldn't have helped) and +`AVE-2026-00066` (hallucinated-name squatting, whose distinction is +explicit: the attack surface is the *model's own hallucination*, not a +human's config choice). This record reads as the generic "pin your +dependencies" case those two more specific records already imply. +#### Decision +JUSTIFY-OR-MERGE +#### Rationale +Candidate for merging into a broader agentic-supply-chain umbrella +alongside 00074/00075/00034/00066, or for an explicit agentic-specific +argument (e.g., agent-authored or agent-approved dependency changes +move at higher velocity and lower human-review depth than +conventional software supply chains, making unpinned drift more likely +to go unnoticed).

Decision: RETAIN. +``` +Capability: An MCP client spawns a server as a subprocess using command/args from configuration data. +Vulnerability: No validation gate exists between untrusted configuration data and the process-spawn boundary. +Impact: Arbitrary OS command execution under the client's privileges before any protocol handshake occurs. +``` + +### AVE-2026-00056 -- Zero-Click Exfiltration via Markdown Image Auto-Fetch +**A** | agent-generated response content → client's automatic +rendering (an unmonitored channel) | No inspection of response content +for embedded exfiltration channels before client rendering acts on it. +Decision: RETAIN. +``` +Capability: Clients automatically render markdown/rich-content references in agent responses. +Vulnerability: No inspection of agent-generated response content for embedded exfiltration channels before automatic rendering fetches them. +Impact: Zero-interaction data exfiltration requiring no tool call and no obfuscation. +``` + +### AVE-2026-00058 -- Deceptive Skill Trigger or Activation-Scope Manipulation +**B** | declared manifest trigger/description → actual implemented +behavior | No verification that declared triggers match real behavior +before invocation decisions are made. Decision: CLARIFY. +``` +Capability: A skill's declared manifest trigger/description determines when it gets invoked. +Vulnerability: No verification checks that a declared trigger matches the skill's actual implemented behavior before invocation. +Impact: Over-broad or implicit invocation in contexts the skill's real behavior does not warrant. +``` + +### AVE-2026-00059 -- Fragmented Cross-Description Prompt Injection (ShareLock-Class) +**A** | per-description review (isolated) → multi-description +composition (never reviewed as a whole) | No cross-description, +holistic review step exists. Real, verified primary source +(ShareLock, arXiv:2606.27027). Decision: RETAIN. +``` +Capability: MCP tool descriptions across multiple tools/servers are individually reviewed for malicious content. +Vulnerability: No cross-description review step exists; review is structurally confined to one description at a time. +Impact: A complete malicious instruction assembles at inference time with no single reviewable artifact ever having existed. +``` + +### AVE-2026-00060 -- STDIO Transport Shell Injection +**E** | tool-call parameters → host shell, in shared SDK code | No +sanitization gate in the shared transport-layer implementation, wholly +independent of agent instruction. Stronger agentic-ecosystem argument +than `00052`/`00053`: this lives in shared MCP SDK code, not one +server's bespoke handler, so the blast radius spans every server built +on an affected SDK. Decision: JUSTIFY, Confidence MEDIUM. +``` +Capability: MCP SDK STDIO transport implementations pass tool-call parameters to a host shell. +Vulnerability: No sanitization gate exists in the shared transport-layer implementation, independent of any agent instruction. +Impact: Remote code execution across every server built on an affected SDK -- a supply-chain-scale blast radius, not one server's bug. +``` + +### AVE-2026-00063 -- Human Approval Gate Bypassed via Declarative Configuration +**A** | instruction-level review (exists) → configuration-level review +(does not exist) | No requirement that safety-relevant config flags +receive the same review rigor as instruction text. Explicitly +differentiated from `00048` in its own text. Decision: RETAIN. +``` +Capability: Components can declare configuration flags controlling whether human approval is required. +Vulnerability: No requirement that safety-relevant configuration flags receive the same review scrutiny as instruction text. +Impact: A required human-in-the-loop control is silently removed with no instruction-level signal a reviewer would catch. +``` + +### AVE-2026-00064 -- Zero-Click Code Execution via Project-Load Auto-Run Configuration +**A** | passive action (opening a project) → code execution, no +confirmation | No confirmation gate on auto-run behavior triggered +passively rather than by explicit tool call. Decision: RETAIN. +``` +Capability: IDE/dev-environment configuration can declare commands to run automatically on project load. +Vulnerability: No confirmation gate exists for auto-run behavior triggered by a passive action rather than an explicit tool call. +Impact: Code execution requiring no action beyond opening a compromised project directory. +``` + +### AVE-2026-00065 -- A2A Agent Card Poisoning +**A** | descriptive capability/identity metadata → instruction, once +loaded into reasoning context | Same metadata-vs-instruction gap as +`00002`/`00041`, in the A2A protocol's genuinely distinct surface (no +`.well-known` path, no `tool.description` field). Decision: RETAIN. +``` +Capability: A host agent reads a remote agent's A2A card to plan task delegation. +Vulnerability: No boundary separates the card's descriptive metadata from executable instruction once loaded into the host's reasoning context. +Impact: Delegation planning hijacked by a malicious remote agent's self-declared, unverified metadata. +``` + +### AVE-2026-00066 -- Hallucinated Skill-Name Squatting (HalluSquatting) +**A** | model's own hallucinated belief → fetch/install action | No +registry-existence or publisher-identity check before acting on a +model-generated resource name. Distinct entry point: no +attacker-controlled content anywhere in the interaction.

Real, citable research (96% success rate). Decision: RETAIN. +``` +Capability: A downstream skill can consume another skill's output as part of its own decision logic. +Vulnerability: No requirement exists for a downstream skill to independently re-verify a trust or authorization claim in an upstream skill's output. +Impact: Harmful actions approved based on a spoofable trust credential no single skill's isolated review would ever catch. +``` + +### AVE-2026-00069 -- Multimodal Image-Hidden Instructions (SkillCamo) +**A** | text-only review pipeline → bundled image resource (never +decoded for review) | No visual/multimodal decoding step exists in +static review. Decision: RETAIN. +``` +Capability: Multimodal agents can decode and act on bundled image content within a skill package. +Vulnerability: No visual/multimodal decoding step exists in the text-only static-review pipeline covering the rest of the package. +Impact: Instructions invisible to every current text-based scanner execute once a multimodal agent processes the resource. +``` + +### AVE-2026-00070 -- Distributed Cross-Agent Backdoor Fragments +**A** | dormant, per-agent fragments → externally reassembled, +post-hoc payload | No anomaly detection for encoded fragments +inconsistent with a tool's stated function, and no cross-agent +correlation of dormant fragments. Decision: RETAIN. +``` +Capability: Tools deliver observations to agents that persist in memory/context after the call. +Vulnerability: No anomaly detection or cross-agent correlation catches a fragmented payload no single session could ever contain enough of to detect. +Impact: A complete backdoor exists and becomes executable only after the fact, entirely outside any single session's visibility. +``` + +### AVE-2026-00071 -- MCP Daemon Redirect via DOCKER_HOST +**A** | expected local daemon → actual, redirected remote daemon +(unverified) | No verification that a declared daemon target matches +the expected local daemon before build/run/pull proceeds. Decision: +RETAIN. +``` +Capability: Components can declare a container daemon connection target via configuration. +Vulnerability: No verification confirms a declared daemon target is the expected local daemon before operations proceed against it. +Impact: Secrets and bind-mounted data are exposed to whatever infrastructure actually receives the redirected connection. +``` + +### AVE-2026-00076 -- Natural-Language Steering of an Approval Classifier Subagent +**A** | steering text (targets the checker) → classifier's approve/deny +judgment | No boundary prevents the same class of natural-language +content that steers a primary agent from also steering the classifier +meant to check it. Decision: RETAIN. +``` +Capability: A committed configuration file can declare natural-language steering text consumed by a safety-classifier subagent. +Vulnerability: No boundary prevents natural-language content from probabilistically steering the classifier meant to check an agent's actions, the same way it steers the agent itself. +Impact: Auto-approval of shell/MCP/Fetch calls the classifier would otherwise flag, via a committed repository file. +``` + +### AVE-2026-00077 -- Cross-Origin Tool and Resource Declaration +**A** | single server's trust boundary → multiple, unrelated actual +origins within it | No per-origin trust segmentation within one +server's own declared manifest. Decision: RETAIN. +``` +Capability: A single MCP server's manifest can declare tools/resources whose URLs span multiple distinct domains. +Vulnerability: No per-origin trust segmentation exists within one server's declared surface. +Impact: A minority-domain tool or resource can hijack context intended for the trusted majority origin, with no deception required. +``` + +### AVE-2026-00079 -- Plan Hijacking via False Completion Signal +**A** | declared plan (N steps) → actual executed trace (fewer steps, +unverified) | No plan-to-execution-trace verification gates a +self-reported completion signal. Decision: RETAIN. +``` +Capability: An orchestrator tracks a declared plan and invokes a final step based on agent-reported status. +Vulnerability: No verification compares the actual executed step count against the declared plan before accepting a self-reported completion signal. +Impact: Remaining planned steps, including verification steps, are silently skipped. +``` + +--- + +## Sprint 4 cross-record consistency finding + +A recurring pattern surfaced across this audit: a large share of AVE's +prompt-injection-shaped records (`00002`, `00016`, `00020`, `00028`, +`00041`, `00043`, `00044`, `00065`) all realize the *same* underlying +vulnerability property -- no boundary distinguishes untrusted content +from instruction -- at *different* attacker-controlled-input surfaces +(tool schema, RAG document, agent-to-agent message, user upload, +server-card, rich UI, async result, A2A card). This is architecturally +coherent, not redundant: Q4 (attacker-controlled input) genuinely +differs for each, and several records already explicitly differentiate +themselves from their nearest neighbors in their own text (`00041` vs. +`00002`, `00065` vs. `00041`, `00044` vs. the rest). The recommendation +is not to merge these, but to name the shared underlying property +explicitly somewhere central (see R-001 in the findings below) so a +reader encounters it as one recognized pattern with many instances, +rather than reconstructing it record-by-record the way this audit had +to. + +A second, smaller pattern: `00019`, `00027`, `00031`, `00035`, `00070` +all use "poisoning" in their titles or descriptions but name four +genuinely different mechanisms (direct memory-store write, instructed +cross-session self-persistence, self-referential feedback-signal +corruption, tool-response fabrication, and dormant multi-agent +fragment reassembly, respectively). Confirmed distinct on inspection, +not a conflation problem -- but worth a shared terminology note so +"poisoning" reads as a family of related-but-distinct mechanisms +rather than implying a single pattern. + +A third pattern, the "unauthenticated in-content claim" family +(`00012`, `00014`, `00030`): false permission grant, false authority +claim, and false role claim all share the identical missing control +(no authentication backs an in-content claim) but differ in exactly +what's claimed and what it unlocks. Confirmed legitimately distinct, +same reasoning as the poisoning family above. + +--- + +## Deliverable 1 — Full 80-record matrix + +| AVE ID | Class | Boundary | Decision | +|---|---|---|---| +|

Recommend a short cross-referencing note (in +`docs/specs/`, not a schema change) naming this as a recognized family, +linking all eight, the same treatment already given to the +"unauthenticated in-content claim" family (00012/00014/00030) and the +"poisoning" family (00019/00027/00031/00035/00070) once this audit +confirmed each was genuinely distinct rather than a labeling accident. + +**R-002, resolve the three structural-decision records deliberately, +not by default.** AVE-2026-00009 (REFRAME), 00032 (REFRAME), and 00038 +(REWRITE) are the only records in the corpus whose current text doesn't +yet name a boundary failure explicitly enough to stand alone. Each has +a real, identifiable mechanism (documented above); the fix is rewriting +the `description`/`behavioral_fingerprint` text, not changing the +`ave_id` or removing the record. Treat as three concrete, scoped +follow-up edits, not a larger project. + +**R-003, get an explicit maintainer decision on implementation-bug +records.** AVE-2026-00052, 00053, and 00060 are pure code-level +implementation flaws in MCP tooling with no agent-instruction or +behavioral component at all -- the records themselves say so. AVE's +value-add for these is a coverage argument (this is part of the +agentic supply chain AVE's consumers already scan, and nothing else in +their pipeline will catch it), not a mechanism-level agentic +distinction. This is a legitimate but different kind of claim than the +rest of the corpus makes, and deserves a deliberate, stated decision +(keep with the coverage rationale made explicit, or scope AVE away from +pure implementation bugs going forward) rather than silence. + +**R-004, revisit the weakest agentic-distinction records as a group.** +AVE-2026-00049, 00061, and 00062 are the three records where a real +agentic-specific argument plausibly exists but isn't yet written down, +and where, absent that argument, each reads as a bare port of an +existing CWE class into an agentic component with no demonstrated +distinction.
