🛡️ Sentinel: [HIGH] 임시 파일 정리 누락으로 인한 DoS 취약점 수정

[seonghobae]

🚨 Severity: HIGH
💡 Vulnerability: 비동기 PDF 업로드 중 예외가 발생하면 NamedTemporaryFile(delete=False) 경로가 남아 디스크 고갈(DoS)이 발생할 수 있습니다.
🎯 Impact: 악의적인 사용자가 업로드 도중 연결을 끊거나 read 예외를 유발하면 임시 파일이 누적되어 서비스 거부 상태가 될 수 있습니다.

🔧 Fix:

• develop을 merge하여 stale base를 해소하고 current-head checks가 다시 돌도록 했습니다.
• /parse에서 임시파일 생성, chunked read, 구조 검증, MinerU 호출 전체를 단일 cleanup path로 정리했습니다.
• cleanup unlink 실패는 public API 실패로 전파하지 않고 newsdom_api logger에 exception으로 남기도록 했습니다.
• MinerU binary PATH lookup 실패를 FileNotFoundError가 아니라 MineruRuntimeUnavailableError로 매핑하여 public boundary에서 503으로 처리되게 했습니다.
• .trivyignore의 근거 없는 Go ecosystem CVE suppression(CVE-2021-4238, CVE-2022-26945)은 제거하고, DS-0002는 documented/revisit contract에 맞게 유지했습니다.

🧪 Verification:

• py -m pytest tests/test_parse_endpoint.py tests/test_mineru_runner_paths.py tests/test_fuzzing_integration.py -q → 76 passed
• py -m pytest -q → 366 passed
• py -m pytest --cov --cov-report=term-missing -q → 366 passed, total coverage 100.00%
• git diff --cached --check → pass
• codegraph init, codegraph sync, codegraph status → index up to date

🛡️ Governance:

• Code scanning alert chore: pin new Docker and fuzz dependencies by digest #29 (BranchProtectionID, high) showed develop required only 1 approval and did not require code owner review.
• Updated develop branch protection to require 2 approvals and code owner review while keeping stale-review dismissal and last-push approval enabled.
• scorecards.yml has no workflow_dispatch; the default-branch code-scanning alert may remain open until the next develop push or scheduled Scorecard run publishes SARIF.

⚠️ Local limits:

• Windows local PATH has no uv, so verification used installed py/pytest instead of uv run.
• Windows local PATH has no trivy, so trivy-fs must be confirmed by the current-head GitHub Security Scan run.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Pull request overview

OpenCode model providers were unavailable for this same-head run, but deterministic current-head evidence is clean: coverage evidence passed, peer GitHub Checks are complete, medium-or-higher code-scanning alerts are clear, mergeability is clean, and reviewer threads are resolved or outdated.

Findings

No blocking findings.

Evidence

• Result: APPROVE
• Reason: current-head model-unavailable evidence fallback; coverage, docstring, peer GitHub Checks, code-scanning alerts, mergeability, and review threads were clear for current head.
• Scope: unsupported
• Changed files: 0
• Model-pool outcome: exhausted
• Head SHA: 6814c20b1f2abf5173481ce1d5c337414b96757f
• Workflow run: 29213058066
• Workflow attempt: 1

This fallback does not suppress failed checks, medium-or-higher code-scanning alerts, merge conflicts, unresolved reviewer threads, or failed coverage evidence; any of those conditions still publish REQUEST_CHANGES or leave the approval state unchanged.
