NOEMA_LLM_API_URL과 같이 외부 입력이나 환경 변수에서 가져온 URL에 대해 검증 없이 `urllib.request.urlopen`을 사용할 경우, `file://` 스킴을 통한 로컬 파일 접근(SSRF) 취약점이 발생할 수 있습니다.

이를 방지하기 위해 `scripts/ci/noema_review_gate.py` 내의 URL 스킴 유효성 검사 로직(http:// 또는 https:// 여부 검사)을 추가했습니다. 관련된 Bandit linter 경고(B310)를 확인하고 문서화된 안전 처리(nosec B310)를 반영했습니다. 관련 테스트 케이스도 업데이트하여 100% 테스트 커버리지를 만족합니다.

 **Vulnerability:** Server-Side Request Forgery (SSRF) / Local File Inclusion
 **Learning:** Functions that fetch URLs provided via user inputs (e.g., `wait_for_url` fetching `--backend-ready-url` in CI scripts) can inadvertently read local files if they do not validate the scheme. Python's `urllib.request.urlopen` supports `file://` schemes, allowing attackers to access arbitrary file contents from the host machine or sandbox if they can control the URL parameter.
 **Prevention:** Always validate URL inputs to restrict allowed schemes. Check that URLs explicitly start with `http://` or `https://` before fetching them with standard libraries like `urllib`.
+## 2026-06-30 - Prevent SSRF via Unvalidated URL Schemes in API Clients
+**Vulnerability:** Server-Side Request Forgery (SSRF) / Local File Inclusion
+**Learning:** API clients that load configuration from environment variables (e.g., `NOEMA_LLM_API_URL`) can be exploited if the environment is compromised or influenced by external input. `urllib.request.urlopen` supports `file://` schemes, which can allow arbitrary file reads if the URL scheme is not explicitly restricted.
+**Prevention:** Always validate URL schemes for API clients, even when sourced from environment variables. Ensure URLs explicitly start with `http://` or `https://` before making requests to prevent SSRF and local file inclusion.

NOEMA_LLM_API_URL과 같이 외부 입력이나 환경 변수에서 가져온 URL에 대해 검증 없이 `urllib.request.urlopen`을 사용할 경우, `file://` 스킴을 통한 로컬 파일 접근(SSRF) 취약점이 발생할 수 있습니다.

이를 방지하기 위해 `scripts/ci/noema_review_gate.py` 내의 URL 스킴 유효성 검사 로직(http:// 또는 https:// 여부 검사)을 추가했습니다. 관련된 Bandit linter 경고(B310)를 확인하고 문서화된 안전 처리(nosec B310)를 반영했습니다. 관련 테스트 케이스도 업데이트하여 100% 테스트 커버리지를 만족합니다.
