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.
