🛡️ Sentinel: Integer Overflow Coercion Vulnerability 수정

[seonghobae]

🚨 심각도: 높음 (High)

💡 취약점

readline() 입력값 검증 시 ^[0-9]+$ 정규표현식을 사용하여 숫자형 문자열을 검증하고 as.integer()로 변환하는 과정에서, 지나치게 큰 숫자가 입력되면 R에서 정수 범위를 초과하여 NA를 반환하는 오버플로우 강제 변환(coercion) 취약점이 발견되었습니다.

🎯 영향

의도하지 않은 큰 수가 입력될 수 있으며, 이 값이 정수로 변환될 때 NA가 되어 이후의 로직(예: 프로세스 크래시)에 치명적인 영향을 미칠 수 있습니다. 악의적이거나 잘못된 입력으로 인해 패키지의 정상적인 실행이 중단될 수 있습니다.

🔧 해결 방법

1과 2 같은 제한적인 선택지를 요구할 때는 정확히 일치하는 범위만 허용하도록 R/aFIPC.R 내의 정규표현식을 ^[12]$ 와 같이 엄격하게 적용하도록 수정하였습니다.

✅ 검증 방법

AFIPC_ENABLE_PACKRAT=true Rscript -e "testthat::test_dir('tests/testthat')" 명령어를 통해 정상적으로 테스트가 성공하는 것을 확인했습니다.

Warning

Review limit reached

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

Next review available in: 26 minutes

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 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.
