Summary
OpenClaw has encoded-path auth bypass in plugin `/api/channels` route classification
Details

Summary (Updated March 2, 2026)

Encoded alternate-path requests could bypass plugin route auth checks for /api/channels/* due to canonicalization depth mismatch in vulnerable builds.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Latest published vulnerable version: 2026.3.1
  • Affected range: <= 2026.3.1
  • Patched release: 2026.3.2 (patched_versions: >= 2026.3.2)

Technical Details

In affected versions, plugin auth-path classification and route-path canonicalization could diverge for deeply encoded slash variants (for example multi-encoded %2f). That mismatch allowed alternate encoded paths to evade protected-prefix auth checks while still resolving to /api/channels/... in plugin route handling.

The fix set hardens this class of issue by:

  • canonicalizing route paths to a bounded fixpoint,
  • failing closed on malformed or unresolved canonicalization depth,
  • requiring explicit plugin-route auth contracts (no implicit auth default),
  • enforcing route ownership/conflict guards for duplicate route registrations, and
  • using shared webhook route lifecycle registration to avoid stale/conflicting route surfaces.

Affected Deployments

Deployments exposing plugin HTTP routes and relying on gateway auth for /api/channels/* protection.
