🛡️ Sentinel: [MEDIUM] 프롬프트 검증 시 발생하는 정수 오버플로우 취약점 수정

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: 사용자의 입력을 as.integer(n)을 통해 변환할 때, grepl("^[0-9]+$", n)와 같이 무한대 크기를 허용하는 정규 표현식으로 인해 integer overflow가 발생하여 NA가 반환되는 보안 이슈를 발견했습니다.
🎯 Impact: 이 과정에서 NA 값이 반환되어 하위 조건 검사에서 에러를 유발하여 프로세스를 비정상 종료시킬 수 있는 리스크가 있습니다.
🔧 Fix: 정규 표현식 기반의 넓은 범위 검증 대신에, n == "1" || n == "2"와 같은 명시적 검증 방식을 사용하여 사전에 원천 차단했습니다.
✅ Verification: test-sentinel-integer-validation.R에 단위 테스트를 추가하여, 거대한 숫자 입력 시에도 overflow 에러가 발생하지 않음을 증명했습니다.
