Summary

• Adds a yarn resolution to force decode-uri-component to 0.5.1, fixing CVE-2026-118664
• CVE-2026-118664 is a quadratic complexity Denial of Service vulnerability (CVSS 7.5) in decode-uri-component < 0.5.1
• The vulnerable package (v0.2.0) was pulled in transitively via query-string and source-map-resolve

Details

Prior to 0.5.1, decodeUriComponent falls back to customDecodeURIComponent after native decoding throws, and the fallback collects every distinct percent-encoded run before performing a full-string regex replacement for each entry. Malformed input containing many distinct runs causes quadratic CPU consumption, blocking the Node.js event loop.

Test plan

• yarn install completes successfully
• decode-uri-component resolves to 0.5.1 in yarn.lock
• CI passes
