In `@app/page.tsx`:
- Line 225: The JSX div in app/page.tsx contains conflicting width classes
`w-[320px]` and `w-full` (the element with className on the <div> that also has
`md:w-[277px]`), so remove the unintended width class—keep the intended
fixed/mobile width (`w-[320px]`) and the responsive `md:w-[277px]`, or if the
intent is full-width on small screens keep `w-full` and remove `w-[320px]`;
update the className to contain only the chosen width to eliminate the conflict.
- Around line 43-53: PainPointTooltip currently uses Tooltip and TooltipTrigger
but omits TooltipContent so the tooltip never appears; fix by either (A) adding
a TooltipContent component inside Tooltip (e.g.,
<TooltipContent>{text}</TooltipContent>) so the hover/trigger shows the intended
text, or (B) if no tooltip behavior is desired, remove Tooltip and
TooltipTrigger and return a plain div with the same classes; update the
PainPointTooltip component accordingly and keep TooltipTrigger asChild only when
TooltipContent is present.
In `@package.json`:
- Around line 19-21: Update the package.json dependency entries for "react" and
"react-dom" to the secure versions (at least 19.2.4) and ensure "next" is at
16.1.6 or newer; modify the values for the "next", "react", and "react-dom" keys
accordingly, then regenerate the lockfile by running your package manager
install (npm/yarn/pnpm) and commit the updated lockfile. After updating, run the
test suite and any CI security/audit steps (npm audit / yarn audit / Snyk) to
verify no remaining vulnerabilities and ensure app builds/starts correctly with
Next.js 16.1.6+ and React 19.2.4.
- Around line 28-30: The package references `@types/node`@^25.1.0 but package.json
lacks an explicit Node.js target; add an engines field to package.json (or
create an .nvmrc) to declare the supported Node.js version and ensure it aligns
with `@types/node` (or else bump/downgrade `@types/node` to match your chosen
runtime); update package.json's "engines" -> "node" to the selected semver range
and/or create an .nvmrc file with the same exact version so developers and CI
use the correct Node.js runtime.

TooltipContent가 누락되어 툴팁이 표시되지 않습니다.
PainPointTooltip 컴포넌트에서 Tooltip과 TooltipTrigger만 사용하고 있지만, 실제 툴팁 내용을 표시하려면 TooltipContent 컴포넌트가 필요합니다. 현재 상태에서는 호버해도 툴팁 내용이 표시되지 않습니다.
툴팁 내용이 의도적으로 필요 없다면 Tooltip 관련 컴포넌트를 제거하고 일반 div만 사용하는 것이 좋겠습니다.

Next.js 16.1.6 security vulnerability fixes January 2026
💡 Result:
Next.js v16.1.6 (published Jan 27, 2026) is not a security release—it’s a bugfix backport (e.g., SWC upgrade and minimal-mode response-cache changes) and does not list any CVE/security fixes of its own. [1]
The security fixes around Jan 2026 for the Next.js 16.x line landed in v16.1.5 (published Jan 26, 2026), which includes patches for:
- CVE-2025-59471 (DoS via memory exhaustion in
/_next/imagewhen external image optimization +remotePatternsare enabled) and CVE-2025-59472 (DoS via memory exhaustion in certain PPR + minimal mode configurations). Fixed in 16.1.5. [2] - CVE-2026-23864 (multiple React Server Components DoS vectors that can lead to crashes / OOM / excessive CPU). Next.js fixed releases include 16.1.5 (plus others). [3]
So, if you’re targeting “the January 2026 security vulnerability fixes” and you’re on Next.js 16.x, the key requirement is upgrade to at least 16.1.5 (and 16.1.6 is fine, since it’s newer). [2][3]
Known-vuln scanners (example: Snyk) list 0 direct vulnerabilities for next@16.1.6 at time of writing, but treat this as advisory/lagging signal rather than a guarantee. [4]

React 19.2.4 release notes security
💡 Result:
React v19.2.4 (released January 26, 2026) includes a security-focused patch for React Server Components / Server Actions—notably “more DoS mitigations … and harden Server Components.” [2]
Security impact (why 19.2.4 matters)
React 19.2.4 is the fixed/backported version for vulnerabilities in the react-server-dom-* packages (react-server-dom-webpack / -parcel / -turbopack) affecting 19.2.0–19.2.3 (and earlier 19.0.x/19.1.x ranges). The React team recommends upgrading immediately. [1]
The issues called out include:
- High severity Denial of Service (infinite loop / hangs, CPU burn; plus additional DoS vectors like crashes/OOM/high CPU depending on code paths): CVE-2025-55184, CVE-2025-67779, CVE-2026-23864 (CVSS 7.5). [1]
- Medium severity Source Code Exposure (leaking Server Function source in certain cases): CVE-2025-55183 (CVSS 5.3). [1]
Who is affected
You’re affected if you run React Server Components / Server Functions on a server using the react-server-dom-* packages. If your app doesn’t use a server (client-only React), React says you’re not affected. [1]
What to do
Upgrade the relevant packages to 19.2.4 (or, for other minor lines, React notes fixed versions 19.0.4 / 19.1.5 / 19.2.4). [1]

React 및 React-DOM 보안 업그레이드 확인됨 - Next.js는 보안 버전 이상으로 업그레이드됨
React 19.2.4와 react-dom 19.2.4는 2026년 1월 26일 발표된 보안 업데이트로, React Server Components/Server Actions에서 발생하는 심각한 거부 서비스(DoS) 취약점들을 해결합니다:
- CVE-2025-55184, CVE-2025-67779, CVE-2026-23864 (CVSS 7.5, DoS 벡터)
- CVE-2025-55183 (CVSS 5.3, 소스 코드 노출)
Next.js 16.1.6(2026년 1월 27일 발표)은 보안 업데이트 버전인 16.1.5 이상이므로 보안 권고사항을 충족합니다. 16.1.5는 /_next/image 및 PPR+minimal 모드에서의 메모리 고갈 DoS 취약점(CVE-2025-59471, CVE-2025-59472)을 수정했습니다.

@types/node 25.1.0 Node.js version requirements compatibility
💡 Result:
@types/node@25.1.0 is the TypeScript declaration set for the Node.js 25.1.x API surface (the major.minor in @types/node tracks Node’s major.minor). It’s therefore the right match when your runtime target is Node 25.1 (or very close to it). [1][2]
Node.js compatibility
- Use
@types/node@25.1.0when you are targeting/running Node.js 25.1.x (Node 25.1.0 was released Oct 28, 2025). [3] - If you target a different Node major (e.g., Node 22 or 24), prefer the matching
@types/nodemajor (e.g.,@types/node@22,@types/node@24) to avoid “types say it exists but runtime doesn’t” (or the reverse). [1][2]
Important nuance
@types/nodeis types-only; it doesn’t “require” a specific Node version at install time in the same way a runtime dependency would. The “compatibility” question is mainly about whether the declared APIs match the Node version you deploy/run. [2]
Practical recommendation
- Pin the major to your runtime line (examples):
@types/node@^25for Node 25,@types/node@^24for Node 24, etc. [2]

프로젝트의 Node.js 버전을 명시적으로 선언하세요.
@types/node@^25.1.0은 Node.js 25.1.x를 대상으로 하는 타입 정의입니다. 현재 package.json에 engines 필드가 없고 .nvmrc 파일도 없으므로, 프로젝트가 실제로 어느 Node.js 버전을 지원하는지 명확하지 않습니다. package.json의 engines 필드를 추가하거나 .nvmrc 파일을 작성하여 필요한 Node.js 버전을 명시해야 합니다.

PAIN_POINTS 중복 문구 정리 여부 확인.
배열 내 동일 문구가 2회씩 있고, 렌더링에서도 2세트를 반복하므로 화면에 동일 문구가 4회 반복됩니다. 의도된 반복이 아니라면 데이터는 유니크하게 유지하고, 이어달리기용 중복은 렌더 단계에서만 처리하는 편이 안전합니다.
