🛡️ Sentinel: [security improvement] 민감한 파일 확장자 정보 노출 방지

[seonghobae]

🚨 Severity: MEDIUM
💡 Vulnerability: 디렉토리 목록(HTML) 생성 시, 백업 파일(.bak, .swp)이나 인증키 파일(.pem, .key 등)과 같이 민감한 정보를 담을 수 있는 파일들이 기본적으로 제외되지 않아 정보 노출(Information Exposure) 위험이 있었습니다.
🎯 Impact: 공격자나 인가되지 않은 사용자가 디렉토리를 탐색하며 중요 시스템 정보, 소스 코드 백업, 또는 인증서 등을 탈취할 수 있습니다.
🔧 Fix: html4tree/main.kt의 process_ignore_file 함수에 동적 필터링 규칙을 추가하여, 널리 쓰이는 민감한 파일 확장자(.pem, .key, .p12, .pfx, .keystore, .bak, .swp 및 ~로 끝나는 백업 파일)들을 디렉토리 목록에서 제외하도록 개선했습니다. 또한, 관련 보안 테스트 코드를 추가했습니다.
✅ Verification: ./gradlew test jacocoTestReport jacocoTestCoverageVerification 명령어를 통해 모든 단위 테스트가 통과하며, 신규 코드의 Jacoco 테스트 커버리지가 100%임을 확인했습니다.

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 660d9a63ca5b572eeb81a2c4d5c1fce6a1882e59.

• Head SHA: 660d9a63ca5b572eeb81a2c4d5c1fce6a1882e59

Closing as superseded by current-base #424. #424 preserves this PR’s key, certificate, keystore, backup, swap, and editor-backup exclusions; adds the union of credential, truststore, database, SQL, log, and packet-capture families; performs locale-stable case-insensitive matching; and has real RED→GREEN evidence on exact head 79c9631abf18adba543cb68ae99759eb0f1ccecb (RED 31482449647; GREEN CI 31482588295, Security 31482588308, SAST 31482588279).
