Bumps fast-uri from 3.1.8 to 3.1.9.

Release notes

Sourced from fast-uri's releases.

v3.1.9

Security

This security release fixes four URI parsing and normalization vulnerabilities in fast-uri 3.x. Applications that process untrusted URI input should upgrade to v3.1.9.

  • Medium — URI scheme spoofing through percent-encoded schemes (GHSA-w74x-v6f9-j3xg, CVE-2026-110306): percent-encoded scheme input is now rejected instead of being decoded into a live scheme.
  • Medium — Host confusion during domain-host canonicalization (GHSA-wjr9-j795-jxcr, CVE-2026-110180): malformed domain hosts containing ambiguous delimiters or stripped control characters are now rejected instead of being silently rewritten.
  • Low — Incorrect relative-reference normalization (GHSA-xhq7-xmqj-769h, CVE-2026-110095): dot-segment removal now preserves the resolution semantics of relative references.
  • Low — Scheme injection in suffix references (GHSA-333x-w4r6-6crp, CVE-2026-110725): first-segment colons in path-only suffix references are now escaped so the output is not reparsed as a scheme.

Upgrade with:

npm install fast-uri@3.1.9

Thanks to @​zekth for reporting the scheme, host, and relative-reference issues, and to @​UlisesGascon for finding the suffix-reference issue and reviewing the remediations.
