🛡️ Sentinel: [MEDIUM] 대화형 입력 폼에 대한 엄격한 숫자 입력 검증 추가

[seonghobae]

🚨 Severity: MEDIUM

💡 Vulnerability:
R/aFIPC.R 내의 checkCorrect, checkoldformBILOGprior, checknewformBILOGprior 함수에서 readline()을 통해 사용자 입력을 받을 때, 검증을 위해 ^[0-9]+$라는 제한 없는 정규 표현식을 사용하고 있었습니다. 이로 인해 9999999999999999999와 같이 과도하게 큰 숫자가 입력될 경우, as.integer() 과정에서 오버플로가 발생하여 NA로 강제 변환되어 의도치 않은 논리 오류나 다운스트림 프로세스 크래시를 유발할 수 있는 취약점이 있었습니다.

🎯 Impact:
악의적이거나 실수로 과도하게 큰 숫자를 입력할 경우, 내부 상태 훼손 및 예기치 못한 애플리케이션 크래시가 발생할 수 있습니다.

🔧 Fix:
사용자 입력을 기대하는 정확한 값('1' 또는 '2')만을 엄격하게 허용하도록 정규 표현식을 ^[0-9]+$에서 ^[12]$로 수정했습니다. 이로써 명확하지 않은 길고 큰 숫자 문자열의 입력을 원천적으로 차단했습니다.

✅ Verification:
모든 로컬 테스트 스위트를 성공적으로 통과하여 코드 변경이 안전하게 적용되었음을 검증했습니다. (Rscript -e "testthat::test_dir('tests/testthat')")

📝 Journal Entry Added:
이와 관련된 취약점 패턴, 학습 내용, 예방 조치를 .jules/sentinel.md에 기록했습니다.

Summary by CodeRabbit

• 개선 사항
  • 대화형 입력에서 허용된 선택지인 1 또는 2만 입력할 수 있도록 검증을 강화했습니다.
  • 잘못된 입력은 유효하지 않은 시도로 처리되며, 최대 3회까지 다시 입력할 수 있습니다.
  • 숫자 변환 오류를 유발할 수 있는 과도하게 큰 값과 형식이 잘못된 입력을 방지했습니다.

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 12b872076eae3a0f6c44c9ee83521a6e7240b851.

Closing as superseded by #193. This branch and #193 change the same three prompt validators to accept only 1 or 2. #193 consolidates the repair with accurate bounded-loop classification, oversized-input and retry-limit regressions, explicit test dependency metadata, and the current fresh-cache R validation fix. Keeping both open would duplicate review and merge work.
