Release notes

Sourced from express's releases.

v4.22.1

What's Changed

[!IMPORTANT]
The prior release (4.22.0) included an erroneous breaking change related to the extended query parser. There is no actual security vulnerability associated with this behavior (CVE-2024-51999 has been rejected). The change has been fully reverted in this release.

PR Review Summary

✅ What looks good

  • Upgrading express from ^4.17.1 to ^4.22.1 is directionally correct for security and maintenance.
  • The lockfile reflects important transitive hardening in the HTTP stack (accepts, cookie, send, http-errors, qs, etc.), which is typically where many CVEs accumulate.
  • Scope at package.json level is minimal (single direct dependency change), which is good intent.

⚠️ Issues found

  • High – lockfile compatibility risk (lockfileVersion: 1 → 3).
    This PR couples an Express upgrade with npm lockfile format migration. If any CI/build/runtime environment still uses older npm, installs may fail or become non-reproducible.
  • High – very large lockfile churn reduces auditability.
    The diff is overwhelmingly lockfile-structure churn plus broad transitive updates, making it hard to confidently review behavior impact for a networking/system component.
  • Medium – dependency policy inconsistency.
    package.json keeps body-parser at ^1.19.0 while lockfile resolves newer transitive body-parser under Express. This can lead to confusing dual-version behavior depending on import path and future lock refreshes.
  • Medium – missing validation evidence for target environments.
    No proof in the diff of npm ci, runtime startup smoke tests, or API regression checks across the actual FireRouter Node/npm matrix.
  • Issue requirement coverage: No linked issue found.

💡 Suggestions

  • Split into two PRs for safer rollout:
  1. Express/security update with minimal lockfile churn,
  2. npm toolchain + lockfile v3 migration.
  • Before merging lockfile v3, explicitly confirm all build/deploy environments support it (document Node/npm versions).
  • Align direct deps with resolved runtime reality (consider bumping body-parser explicitly to a compatible maintained version, or remove direct usage if unnecessary).
  • Attach verification artifacts:
  • clean npm ci,
  • service startup,
  • core API smoke tests (request parsing, routing, error handling).
