security: Sprint 0 emergency fixes - #42
Conversation
…quest limits, localhost default - Replace str(exc) with generic 'internal server error' in all API error responses (agent_engine/api/app.py, agent_manager/api/routes.py) - Add non-root USER agent to Dockerfile - Add Pydantic max_length constraints to all request schema string fields - Default --host to 127.0.0.1 in agentctl serve and agent_manager config - Add docker-compose.yml with engine (8090) and manager (8100) services, SQLite volume, health checks - Add tests/e2e/test_sprint0.py — 22 tests verifying all Sprint 0 fixes - Add docs/SECURITY_SPRINTS.md — remediation plan from security audit

Review Responses
Dockerfile /workspace doesn't exist at chown time (Comment #3633257354)
Good catch fixed. Added RUN mkdir -p /workspace before the chown in commit 48952ce.
app.py exceptions swallowed without logging (Comment #3633310180)
Added logger.exception() before the generic error response in �gent_manager/api/routes.py. Both the sync and streaming error paths now log the full traceback server-side while returning a generic message to the client. �gent_engine/api/app.py already had this it was only missing in
outes.py.
schemas.py message limits should derive from LLM context window (Comment #3633324735)
Agreed. The max_length=65536 here is defense-in-depth at the Pydantic layer, not a substitute for proper context-window-aware limits. This should be wired to context_max_tokens / context_max_chars from Settings. Tagging for Sprint 2.
Tests are static source checks, not e2e (Comment #3633330987)
Renamed to ests/test_sprint0_static_checks.py with a clarifying docstring. These are source-level pattern checks, not integration tests.
Dockerfile did you run locally? Does entrypoint.sh work? (Comment #3633342557)
The dev environment has Python 3.10 cannot build the Docker image locally (requires 3.11). The docker build needs to be tested in CI or on a machine with Docker + Python 3.11. The USER agent directive is standard non-root practice; entrypoint.sh uses chmod +x which runs as root before USER agent is set.
schemas.py Field(max_length) is not a true HTTP body size limit (Comment #3633352075)
Correct. This is defense-in-depth at the Pydantic layer. True HTTP body size limits should be enforced at the ASGI/proxy layer. Tagging for Sprint 2 in docs/SECURITY_SPRINTS.md.
routes.py must log the error (Comment #3633359098)
Fixed. Added logger.exception() before both generic error responses in
outes.py.
docker-compose.yml services unreachable due to 127.0.0.1 (Comment #3633397149)
Reverted the CLI/config defaults back to 0.0.0.0. Compose now explicitly passes --host 0.0.0.0 inside containers. Host-side ports are bound to 127.0.0.1:port:port for local-only access.
main.py reconsider 127.0.0.1 default bind address (Comment #3633414669)
Reverted. Default is back to 0.0.0.0. Network security is controlled by the container platform, not the application bind address.
docker-compose.yml comprehensive review (Comment #3633441163)
All points addressed:
- Containers now pass --host 0.0.0.0 explicitly.
- Ports bound to 127.0.0.1:port:port.
- SQLite volume removed not part of the deployment model.
- Health checks updated to use 127.0.0.1 inside containers.

the manager still defaults to sqlite+aiosqlite:///chat.db and runs migrations on startup. Since /workspace is mounted as read-only, it will attempt to create /workspace/chat.db and fail unless an external database URL is explicitly provided.
There was a problem hiding this comment.
Fixed. The manager service now sets \DATABASE_URL=sqlite+aiosqlite:////data/chat.db\ with a writable named volume mounted at /data\ (outside the read-only /workspace), so migrations no longer try to write /workspace/chat.db. This compose is explicitly local-dev only; production deployments point DATABASE_URL at a client-owned database.

This does not match the current architecture.
Extra does not currently provide an API authentication plugin. The AccessResolver performs authorization after a verified caller identity has already been supplied; it does not validate API keys or JWTs at the HTTP boundary.
This should explain that authentication is handled by the client gateway, host application, or API middleware, and that the verified identity/context is then passed to Extra for access-control decisions.
It can be done by the corporate using the hooks feature.
When the user decides to invoke functionality because of a specific activity (like every request), he can make logic that makes the authentication and change in the YAML the error level (instead of warning)

Agreed the wording was wrong and I've corrected it. The SECURITY.md now states Extra does not validate API keys/JWTs itself; authentication is the client gateway/host/middleware's job, and the verified identity/context is passed into Extra (e.g. via the runtime hooks feature) for access-control decisions. Updated the known-gaps table, the deployment recommendation, and added the SIDECAR_CONTEXT_AUTH.md pointer.

This should be described as request-field length validation, not as a complete HTTP request-size limit.
Pydantic validates the field only after the request body has already been read and parsed. It is also not currently applied to all request string fields, for example ApprovalDecisionRequest.user_id and ApprovalDecisionBody.decision.
There was a problem hiding this comment.
Agreed. SECURITY.md now describes this accurately as request-field length validation (Pydantic max_length, applied after the body is parsed), not a full HTTP body-size limit, and notes the ASGI/proxy-level limit is planned in Sprint 2. I also closed the two gaps you called out: ApprovalDecisionRequest.user_id and ApprovalDecisionBody.decision now carry Field(max_length=128).

Do we need commit this file? if we handle only sprint 0 now, and have more gaps, you can open an issue for other or just create fix PR :)

We'd like to keep it in this PR: it's the tracking doc for the audited gaps and maps each finding to a sprint + status, which gives reviewers and users a single place to see what's open. The future sprints are tracked as ordered work inside the same file rather than separate issues, so nothing is silently dropped. Happy to split into issues if you prefer.

We chose to keep SECURITY.md in this PR after fixing the two accuracy issues you raised (auth architecture and request-field-length wording) it also now covers the missing approval-field bounds. If you still want it moved out to a separate PR, say the word and we'll split it.
