🛡️ Sentinel: [HIGH] 세션 내보내기에서 CSV 수식 주입 취약점 수정

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: 세션 내보내기(CSV) 기능에서 사용자 입력값이 엑셀 등의 스프레드시트 프로그램에서 수식(매크로)으로 인식될 수 있는 취약점(CSV Formula Injection / Spreadsheet Macro Injection)이 존재했습니다.
🎯 Impact: 악의적인 사용자가 첫 글자를 =, +, -, @, \t, \r 등으로 시작하는 값을 입력한 후 다른 관리자가 해당 CSV 파일을 엑셀 등에서 열었을 때 임의의 명령어나 수식이 실행되어 데이터 유출이나 악성 코드 실행 등의 피해가 발생할 수 있습니다.
🔧 Fix: csvField 유틸리티 함수를 생성하여, 숫자 타입이 아니면서 위험한 문자로 시작하는 값은 앞에 단일 인용부호(')를 추가하여 문자열로 처리하도록 강제했습니다.
✅ Verification: pnpm --filter @argos/web run test --coverage 명령어를 통해 유틸리티 함수의 동작을 100% 테스트 커버리지로 검증했습니다.
