fix(deps): patch 4 npm security vulnerabilities via overrides#367
Merged
Conversation
Closes Dependabot alerts #36 (form-data CRLF injection), #37 (ws@7 memory exhaustion), #38 (ws@8 memory exhaustion), #39 (js-yaml@3 quadratic DoS). All fixes use package.json overrides — no direct dependency changes: - form-data: ^3.0.4 → ^3.0.5 (CRLF injection in multipart field names) - ws (global, jsdom dep): 7.5.10 → 7.5.11 (memory exhaustion DoS) - ws (webpack-dev-server nested): >=8.20.1 → >=8.21.0 (same CVE, 8.x series) - js-yaml: ^4.2.0 (quadratic DoS in merge key handling; js-yaml resolves to 4.3.0 for all dependents, including the former 3.14.2 root copy) Production build verified clean after changes.

Change exact pin '7.5.11' to '^7.5.11' for consistency with all other overrides in the file. Resolved version is unchanged (still 7.5.11). Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013S7BMjyXGSNLYkfFDWomuj
…ad breakage svgo@1.3.2 calls yaml.safeLoad() which was removed in js-yaml@4. Add a nested override to give svgo its own js-yaml@3.x while all other consumers get v4. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_013S7BMjyXGSNLYkfFDWomuj

Summary
Patches 4 npm security vulnerabilities in the CRA frontend dependency tree using
package.jsonoverrides. No application code changed.Vulnerabilities fixed
form-data(CRLF injection)^3.0.5(patched from 3.0.4)ws@7(memory exhaustion)^7.5.11(patched from 7.5.10)ws@8in webpack-dev-server (memory exhaustion)>=8.21.0insidewebpack-dev-serverjs-yaml(quadratic expression DoS)^4.2.0; scoped away fromsvgo@1.3.2(see below)js-yaml: why there's a nested svgo override
svgo@1.3.2(pulled in by CRA's SVGR pipeline) callsyaml.safeLoad(), which was removed in js-yaml@4. A flat"js-yaml": "^4.2.0"override would silently break any build that processes an SVG import. The fix: a nested"svgo": {"js-yaml": "^3.14.2"}override gives svgo its own js-yaml@3.x while all other consumers get v4.Verified:
svgo/node_modules/js-yaml@3.15.0(safeLoad works), rootjs-yaml@4.3.0(load works).Vulnerabilities intentionally NOT fixed
These remain open; they require a
react-scriptsmajor version bump or CRA→Vite migration, which is out of scope for this PR:webpack-dev-server@4.15.2— 4 moderate CVEs (GHSA-9jgg-88mc-972h, -4v9v-hfq4-rm2v, -79cf-xcqc-c78w, -mx8g-39q3-5c79). Fix requires wds ≥5.2.5, locked by CRA.@babel/core— 1 low CVE. Fix requires major version bump, locked by CRA.http-proxy-middleware— 1 moderate CVE. Fix requires a CRA-breaking major bump.The ws @8 bump addresses the WebSocket-layer DoS in wds; the remaining wds CVEs are in wds's own application code.
