🛡️ Sentinel: [HIGH] Fix CSV Injection (Spreadsheet Macro Injection) Vulnerability

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: 사용자가 입력한 데이터(세션 이름 등)가 CSV 내보내기 기능에서 특수 문자(예: =)로 시작될 경우, 해당 CSV를 Excel 등의 스프레드시트 앱에서 열었을 때 수식 또는 매크로로 실행될 수 있는 CSV 인젝션(Spreadsheet Macro Injection) 취약점이 발견되었습니다.
🎯 Impact: 악의적인 사용자가 특수 문자로 시작하는 프로젝트나 제목을 작성할 경우, 이 데이터를 CSV로 내보내 열어보는 관리자나 다른 사용자의 시스템에서 임의 코드가 실행될 위험이 있습니다.
🔧 Fix: CSV의 필드를 생성할 때, = + - @ \t \r 로 시작하는 경우 값의 맨 앞에 단일 인용부호(')를 삽입하여 스프레드시트가 이를 수식이 아닌 텍스트로 인식하게 만들었습니다. 로직은 lib/server/csv.ts로 분리하였고 테스트를 포함시켰습니다.
✅ Verification: pnpm --filter @argos/web run test src/lib/server/csv.test.ts --coverage를 통해 100% 코드 커버리지가 달성되었음을 확인하였으며, pnpm test 및 pnpm lint를 통해 다른 기능이 정상 동작함을 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: 31 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.
