🛡️ Sentinel: [CRITICAL] 정수 오버플로 취약점 수정

[seonghobae]

🚨 Severity: CRITICAL
💡 Vulnerability: 대화형 readline() 입력을 받을 때, 무한한 숫자 문자열 패턴(^[0-9]+$)으로 입력값을 검증했습니다. 이 경우 사용자가 매우 큰 숫자를 입력할 때 as.integer() 함수가 정수 오버플로를 일으켜 NA를 반환하게 되며, 이에 대한 예외 처리가 없어 프로세스가 예기치 않게 종료되거나 강제 변환에 의한 논리적 오류가 발생할 수 있습니다.
🎯 Impact: 악의적인 사용자가 과도하게 긴 숫자를 지속적으로 입력하거나 자동화된 입력 스크립트를 통해 패키지 실행 흐름을 방해하거나 DoS(서비스 거부)를 유발할 위험이 있습니다.
🔧 Fix: aFIPC.R 내 3곳의 readline() 입력 검증 코드를 수정하여, (1: Yes 2: No) 선택에 맞게 ^[12]$ 값만 허용하도록 명시적인 엄격한 값 검증을 적용했습니다.
✅ Verification:

1. R 패키지를 빌드하고 로드합니다.
2. 대화형 환경에서 aFIPC 모형 추정 함수를 실행하며 1 또는 2 이외의 값을 입력했을 때 거부되는지 확인합니다.
3. testthat::test_dir('tests/testthat')을 실행하여 모든 테스트를 통과하는지 확인했습니다 (총 55개 테스트 모두 Pass).

👋 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: 12 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.

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 3bf1734326d398eaf24dadf1b98848a23d82ba0f.

• Head SHA: 3bf1734326d398eaf24dadf1b98848a23d82ba0f
