fix(deps): remove unused @jsfeb26/urllib-sync (Dependabot #129) - #322
Merged
Conversation
Fixes GHSA-hq3h-g68c-hp78 / CVE-2026-55553 (Dependabot alert #129): transitive urllib <=2.44.0 preserves credential-bearing headers (Authorization, Cookie, etc.) across cross-origin redirects. @jsfeb26/urllib-sync was the sole package pulling in the vulnerable urllib@2.11.1, and it is not referenced anywhere in the codebase (added in 2021 as a fork of urllib-sync, never used since). Removing it as dead weight eliminates the vulnerable transitive dependency entirely rather than forcing an override against its ~2.11.0 pin. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>

Summary
Fixes Dependabot alert #129 — GHSA-hq3h-g68c-hp78 / CVE-2026-55553 (high, CVSS 7.5).
urllib<= 2.44.0 preserves credential-bearing headers (Authorization,Cookie,Proxy-Authorization, etc.) verbatim when following a cross-origin redirect, which can leak credentials to an untrusted origin.Root cause
@jsfeb26/urllib-sync(pinned to~2.11.0, added in 2021) was the only dependency pulling in the vulnerableurllib@2.11.1. A repo-wide search found no references to it anywhere in the codebase — it's dead weight.Fix
Removed
@jsfeb26/urllib-syncfrompackage.jsonand regeneratedpackage-lock.json. This drops the vulnerable transitiveurllibentirely, rather than forcing a version override against its tight semver pin.Verification
