🛡️ Sentinel: [HIGH] aFIPC.R 파일의 대화형 입력값 검증 정규표현식 수정 (정수 오버플로우 취약점 방지)

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: readline() 입력값을 검증할 때 경계가 없는 정규표현식(^[0-9]+$)을 사용하여, 지나치게 큰 숫자가 입력될 경우 as.integer()에서 NA가 반환되어 이후 프로세스가 중단되거나 예상치 못한 동작(정수 오버플로우로 인한 DoS)을 유발할 수 있습니다.
🎯 Impact: 잘못된 입력이나 악의적인 큰 숫자로 인해 실행 도중 런타임 에러가 발생하거나 서비스 거부(DoS) 상태가 될 수 있습니다.
🔧 Fix: 입력값을 검증하는 정규표현식을 ^[12]$로 수정하여 허용된 정확한 숫자 '1' 또는 '2'만 입력받도록 강제했습니다.
✅ Verification: 단위 테스트(testthat)를 전체 수행하여 모든 테스트가 정상적으로 통과(PASS)하는 것을 확인했으며 패키지가 오류 없이 빌드되었습니다. 추가로 .jules/sentinel.md 저널에 보안 학습 내용을 기록했습니다.

👋 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: 25 minutes

Limit details: You’ve used the included review currently available.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

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 within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 8b55d4c50fcf78a088e14c29cd41e993b536c1dd.
