open GHSA 4q39 PR

Objective: Open a PR for the GHSA-4q39 @platejs/docx-io hotfix. Done means repo check passed, the full checkout was committed and pushed on a codex/ branch, the PR exists, the PR body was read back and verified as public-safe, and this goal plan checker passes.

Completion threshold:

• pnpm check passes in /Users/zbeyens/git/plate.
• The full checkout is staged, committed, pushed, and represented by PR #5053.
• gh pr view 5053 --json body,url,headRefName,isDraft,title verifies the task-style PR body.
• node .agents/skills/autogoal/scripts/check-complete.mjs docs/plans/2026-07-03-open-ghsa-4q39-pr.md passes before closing the goal.

Verification surface:

• Root repo verification: COREPACK_DIR="$(dirname "$(command -v corepack)")"; PATH="$COREPACK_DIR:$PATH" pnpm check in /Users/zbeyens/git/plate.
• GitHub verification: gh pr view 5053 --json body,url,headRefName,isDraft,title.
• Existing package/security proof: docs/plans/2026-07-03-triage-ghsa-4q39-docx-io.md.
• Browser verification: N/A because the change is a server-side package export path, not an app route or UI.

Constraints:

• User explicitly authorized commit, push, and PR creation.
• PR must use the entire current checkout as-is, including untracked files.
• Public PR and advisory text must omit exploit steps, payloads, and reproduction details.
• No release publish, advisory publication, or CVE request in this PR lane.

Boundaries:

• Source of truth: user request, repo PR rules, completed GHSA triage plan, local checkout, and GitHub PR readback.
• Code ownership: @platejs/docx-io package default behavior.
• Tracker sync: GHSA draft was already redrafted and left unpublished; no public tracker comment is needed.
• Release order: merge PR, publish patched package, update GHSA patched version metadata, request CVE, then publish advisory.

Blocked condition: No blocker remains. GitHub auth, push, PR creation, and PR body readback succeeded.

Task state:

• task_type: PR shipping
• task_complexity: normal
• current_phase: closeout
• current_phase_status: complete
• next_phase: final response
• goal_status: ready for completion after checker pass

Current verdict:

• verdict: complete pending mechanical checker
• confidence: high
• next owner: maintainer review / merge
• reason: root check passed, branch pushed, PR opened, and body verified.

Pre-solution issue challenge:

• reporter claim: GHSA reports unsafe default remote image fetching in @platejs/docx-io.
• validity verdict: valid package vulnerability by prior source audit and regression proof.
• best long-term fix boundary: disable remote image fetching by default in the package, with explicit opt-in for trusted HTML.
• hard-stop decision: ship sanitized PR first; release/advisory publication follows patched package availability.

Phase / pass table:

Phase	Status	Evidence	Next
Intake and source read	complete	User request and repo rules read	check
Implementation	complete	Existing hotfix and plan files committed	verification
Verification	complete	Root pnpm check passed	PR
PR / tracker sync	complete	PR #5053 opened and body verified; tracker sync N/A	closeout
Closeout	complete	Plan checker next, then goal complete	final response

Findings:

• Root pnpm check passed before PR creation.
• PR #5053 is ready and non-draft.
• PR #5053 head branch is codex/ghsa-4q39-docx-io.
• PR body is sanitized and does not include exploit steps, payloads, or code-location walkthroughs.

Decisions and tradeoffs:

• Used a package default fix instead of caller-side filtering because the package owns remote image fetch behavior.
• Kept GHSA patched version metadata, CVE request, and advisory publication out of this PR because the patched npm version does not exist yet.

Implementation notes:

• Initial commit: 8a66d6c4dd1b with full checkout staged.
• Branch: codex/ghsa-4q39-docx-io.
• PR: https://github.com/udecode/plate/pull/5053.

Review fixes:

• None needed in this PR lane.

Verification evidence:

• COREPACK_DIR="$(dirname "$(command -v corepack)")"; PATH="$COREPACK_DIR:$PATH" pnpm check passed in /Users/zbeyens/git/plate.
• git push -u origin codex/ghsa-4q39-docx-io succeeded.
• gh pr create --base main --head codex/ghsa-4q39-docx-io --title "Fix DOCX remote image export default" created https://github.com/udecode/plate/pull/5053.
• gh pr view 5053 --json body,url,headRefName,isDraft,title,headRefOid verified head branch codex/ghsa-4q39-docx-io, isDraft: false, URL, preserved auto-release block, and sanitized task-style body.
• node .agents/skills/autogoal/scripts/check-complete.mjs docs/plans/2026-07-03-open-ghsa-4q39-pr.md passed.

Final handoff contract:

• PR line: https://github.com/udecode/plate/pull/5053
• Issue / tracker line: GHSA draft already redrafted and left unpublished; no public tracker sync needed.
• Confidence line: high; check, push, PR creation, and body verification passed.
• Flow table:
  • Reproduced: source/test proof in prior GHSA plan; browser N/A.
  • Verified: root pnpm check; browser N/A.
• Browser check: N/A, server-side package export path.
• Outcome: remote image fetching is disabled by default in @platejs/docx-io DOCX export, with explicit trusted opt-in.
• Caveat: publish patched npm version, update GHSA metadata, request CVE, and publish advisory after merge/release.
• Design:
  • Chosen boundary: package default behavior.
  • Why not quick patch: caller-side filtering would leave unsafe defaults elsewhere.
  • Why not broader change: package-level default closes the risky behavior without unrelated API churn.
• Verified: pnpm check; GHSA draft public-safe; PR body readback public-safe.
• PR body verified: yes, via gh pr view 5053 --json body,url,headRefName,isDraft,title,headRefOid.

Task-style PR body contract:

• Body preserves the repo auto-release block, then starts task content with 🐛 Fixes GHSA-4q39-2jhr-7qx8.
• Body includes 🟢 95-100% confidence.
• Body includes | Phase | 🧪 Tests | 🌐 Browser |.
• Body includes Reproduced and Verified rows.
• Body includes **✅ Outcome**, **⚠️ Caveat**, **🏗️ Design**, and **🧪 Verified**.
• Body does not link to itself.

Final handoff / sync:

• PR: https://github.com/udecode/plate/pull/5053
• Issue / tracker: GHSA draft updated privately; no public tracker comment.
• Browser proof: N/A, no browser-owned surface.
• Caveats: release/advisory/CVE work remains after merge and patched package publish.
