Pin transitive js-yaml to ^5.2.1 via pnpm override to remediate GHSA-5p4m-2wfm-xmqj (CVE-2026-59870 fix never backported to 3.x/4.x lines). js-yaml is a dev-only transitive dependency (jsdom, @eslint/eslintrc, confbox, katex, toml-eslint-parser); resolved version is 5.2.3. Verified lint (0 errors), tsc --noEmit, vitest (1298 passed), and vite build all pass unchanged with the override applied.

Summary
Remediates GHSA-5p4m-2wfm-xmqj (High) — quadratic CPU consumption in
!!omapresolution affecting js-yaml 3.x and 4.x. This is the same weakness as CVE-2026-59870 (GHSA-724g-mxrg-4qvm), fixed upstream in the 5.x line at 5.2.1, but never backported to the 3.x/4.x legacy lines.Change
Pins the transitive
js-yamldependency to^5.2.1via apnpm-workspace.yamloverride, following the same pattern as the existingfast-urioverride. Resolved version: 5.2.3.js-yamlis a dev-only transitive dependency here (pulled in by@eslint/eslintrc,jsdom,confbox,katex,toml-eslint-parser) — it only parses trusted local config/build-time YAML, not untrusted user input, but the fix is minimal and reversible so it's included per the security remediation scope.Verification
All quality gates pass unchanged with the override applied:
pnpm lint— 0 errors (44 pre-existing warnings, unchanged)pnpm exec tsc --noEmit— cleanpnpm test— 1298 passed / 57 files, 0 failedpnpm build— tsc + vite build succeededRemoval criteria
Remove this override once all transitive consumers (
@eslint/eslintrc,jsdom,confbox,katex,toml-eslint-parser) bump their ownjs-yamlrequirement past 5.2.1.🤖 Generated by Fro Bot autohealing (schedule-95a0d398-31239756521).
