🛡️ Sentinel: [CRITICAL] 프로젝트 ID 경로 탐색(Path Traversal) 취약점 수정

[seonghobae]

🚨 Severity: CRITICAL
💡 Vulnerability: 사용자가 제공한 projectId 값이 검증 없이 분석 엔진 내의 경로로 사용될 수 있는 경로 탐색(Path Traversal) 취약점이 발견되었습니다.
🎯 Impact: 악의적인 사용자가 . 이나 .., 또는 디렉토리 구분자(/, \)를 포함한 projectId를 전송하면, 백엔드 파일 시스템의 의도치 않은 파일에 접근하거나 덮어쓸 수 있습니다.
🔧 Fix: projectId 검증 과정에서 . 이나 ..와 정확히 일치하거나 디렉토리 구분자를 포함하는 경우 ValueError를 발생시키고 경고 로그를 남기도록 수정했습니다. (my..id 와 같은 일반적인 식별자는 정상적으로 처리됩니다.)
✅ Verification: 관련 방어 로직에 대한 테스트 케이스(test_validate_analysis_job_request_rejects_bad_payloads, test_validate_analysis_job_request_accepts_local_audio_payload)를 추가하여, 정상적인 경우와 악의적인 경우 모두 100% 테스트 커버리지를 통과함을 확인했습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 15 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Closing as closed-duplicate/superseded (path-traversal cluster) by autonomous product-completion loop.

Winner / disposition target: #727

Unique value from this cluster is consolidated there (projectId path guard + npm HIGH CVE pins + Foote novelty kernel sign). Remaining micro-duplicates do not land additional commercial readiness.
