fix(security): remove extract-zip CVE-2026-56876 via unused LHCI dep by iDorgham · Pull Request #258 · iDorgham/Gateflow

iDorgham · 2026-08-13T16:17:45Z

Summary

Closes Dependabot alert #143: extract-zip@2.0.1 (CVE-2026-56876, HIGH). There is no patched extract-zip release.
Removes unused workspace @lhci/cli, which was the only path to extract-zip (@lhci/cli → Lighthouse → Puppeteer → @puppeteer/browsers).
Lighthouse CI is unchanged: .github/workflows/lighthouse.yml already installs @lhci/cli globally. Local runs: npx --yes @lhci/cli@0.14.0 autorun --config=.lighthouserc.js.

image-size alerts #141/#142 stay dismissed (already acknowledged in pnpm check:security:fail).

Test plan

extract-zip and puppeteer-core absent from pnpm-lock.yaml
pnpm check:security:fail clean (acknowledged image-size only)
pnpm install --frozen-lockfile
pnpm docs:changelog:check
Pre-push preflight (lint/typecheck/test) passed
After merge, confirm Dependabot alert build(deps): bump the react-stack group with 2 updates #143 auto-closes

Changes

LHCI dependency cleanup

Layer / File(s)	Summary
Remove workspace dependency and update LHCI configuration `package.json`, `.lighthouserc.js`	The root package removes `@lhci/cli`. The Lighthouse configuration documents global CI installation and local `npx` usage. Local JSDoc typedefs define the Lighthouse CI configuration shape.
Record dependency removal `CHANGELOG.md`	The Unreleased changelog records removal of the unused dependency and continued global LHCI installation in CI.

Estimated code review effort: 2 (Simple) | ~10 minutes

Mergeability Score: 🔵 Low · up to 3b269

The PR removes an unused dependency and updates CI configuration, but the Lighthouse configuration still has weak type validation. It is mergeable with explicit owner awareness and follow-up to strengthen configuration validation.
