🚨 Severity: MEDIUM
💡 Vulnerability: FastAPI multipart/form-data 처리 시 문자열 입력 길이에 대한 제한이 없어 메모리 고갈(DoS) 공격에 취약함
🎯 Impact: 악의적인 사용자가 매우 긴 문자열 데이터를 전송하여 애플리케이션의 메모리를 고갈시키고 서비스를 마비시킬 수 있음
🔧 Fix: language 및 mode 폼 필드에 max_length=50을 적용하여 무제한 페이로드 입력을 방지함
✅ Verification: 길이가 51 이상인 문자열을 전송할 때 422 상태 코드를 반환하는지 테스트 코드를 작성하여 검증함
