🚨 Severity: HIGH
💡 Vulnerability: The component library gallery (components/index.html) lacked a Content Security Policy (CSP), leaving it potentially vulnerable to XSS and framing attacks. It also relied heavily on inline scripts (<script>...) and inline styles (<style>...</style>, style="...").
🎯 Impact: An attacker could potentially inject malicious scripts or styles into the component gallery context, or embed the page maliciously.
🔧 Fix:

  1. Added a strict CSP meta tag (default-src 'self', object-src 'none', style-src 'self', etc.) and a Referrer-Policy to components/index.html.
  2. Extracted the inline <script> into components/krds-gallery.js and loaded it with defer.
  3. Extracted the inline <style> into components/krds-gallery.css.
  4. Refactored inline style="..." HTML attributes into reusable CSS utility classes (e.g., .mt-16, .max-w-320) in krds-gallery.css.
  5. Permitted data: URIs in img-src to allow the inline SVG icons used within krds-components.css.
    Verification: Playwright tests confirm that the console no longer throws CSP blocking errors when loading the gallery.

Pull request overview

OpenCode reviewed the current-head mergeability evidence and changed-file flow before approval, then found merge conflicts on the affected path.

Findings

1. HIGH Merge Conflict Guidance - Resolve the PR branch against the latest base branch

  • Problem: GitHub reports mergeStateStatus DIRTY for this pull request.
  • Root cause: Branch sentinel/strict-csp-component-gallery-18356632995419362895 cannot be merged cleanly into main; the changed-file flow below shows which review/runtime path is blocked by the conflict.
  • Fix: Merge or rebase the latest main into sentinel/strict-csp-component-gallery-18356632995419362895, resolve conflict markers in the PR branch, rerun the focused checks, and push the same branch.
  • Repair commands:
gh pr checkout 77 --repo ContextualWisdomLab/ContextualWisdomLab.github.io
git fetch origin main
git merge --no-ff origin/main # or: git rebase origin/main
git status --short
# resolve files, then git add <resolved-files># merge path: git commit# rebase path: git rebase --continue
git push origin HEAD:sentinel/strict-csp-component-gallery-18356632995419362895
# rebase path only: git push --force-with-lease origin HEAD:sentinel/strict-csp-component-gallery-18356632995419362895
  • Regression test: Keep OpenCode approval gated on mergeability so model-output failures cannot approve a conflicted PR.

Pull request overview

OpenCode could not approve from deterministic current-head evidence because GitHub Checks have failed.

Findings

1. HIGH Current-head GitHub Checks - Fix failed required checks before approval

  • Problem: Failed same-head checks remain for 7837ff379bc93eb0d30d70195c39fbf29935ce2b.
  • Root cause: The model-unavailable evidence fallback is allowed only when peer GitHub Checks are complete and clean.
  • Fix: Read and fix the failed check logs below, then rerun the current-head checks.
  • Regression test: Keep the model-unavailable fallback gated on an empty failed-check rollup.

Rebuilt on current main@4c9241c8de1fde19ae2646dbcb52e796feaa38e7 and pushed as exact head c175eba944c162667327340936b0dc472fc745a9.

Current-head changes and evidence:

  • Extracted all gallery inline style blocks, style attributes, and scripts into same-origin krds-gallery.css and krds-gallery.js.
  • Enforced default-src none, explicit same-origin script/style/font/connect directives, data images only, no object/base/form/frame targets, HTTPS upgrades, and Trusted Types.
  • Added strict referrer policy and regression guards for CSP directives, inline active content, event attributes, and unsafe DOM sinks.
  • TDD: 3 failures before the CSP extraction; 5 tests pass after the fix.
  • Coverage: 50 statements, 100 percent.
  • Trivy CRITICAL/HIGH/MEDIUM vulnerability, misconfiguration, and secret findings: 0.
  • Prior CodeQL failure was a no-source configuration error on the stale conflicting head; current main supplies Python test source for extraction.
  • Open review threads: 0.

중앙 OpenCode review queue cadence 수정(ContextualWisdomLab/.github#495)이 병합되었습니다. 코드나 HEAD를 변경하지 않고, 이전 장시간 model-pool 실행을 종료하고 새 10분 provider / 30분 step 예산으로 current HEAD 검증을 다시 시작합니다.

Current HEAD에 추가된 dede9dd 커밋이 엄격한 CSP 지시어를 약화하고 보안·성능 회귀 테스트와 content-visibility 최적화를 삭제한 것을 확인해 2fadd27에서 복원했습니다. CodeGraph를 초기화·동기화했고, pytest 5개 PASS, 집중 coverage 100%, Trivy Medium/High/Critical vulnerability·misconfiguration·secret 0입니다. 현 HEAD 전체 Checks와 리뷰를 다시 검증합니다.
