CVE-2026-32036
OpenClaw < 2026.2.26- Authentication Bypass via Encoded Dot-Segment Traversal in /api/channels
OpenClaw gateway plugin versions prior to 2026.2.26 contain a path traversal vulnerability that allows remote attackers to bypass route authentication checks by manipulating /api/channels paths with encoded dot-segment traversal sequences. Attackers can craft alternate paths using encoded traversal patterns to access protected plugin channel routes when handlers normalize the incoming path, circumventing security controls.

8.3
OpenClaw has gateway plugin auth bypass via encoded dot-segment traversal in protected /api/channels paths
Summary
Gateway plugin route auth protection for /api/channels could be bypassed using encoded dot-segment traversal (for example ..%2f) in path variants that plugin handlers normalize.
Affected Packages / Versions
- Package: npm
openclaw - Latest published vulnerable version:
2026.2.25 - Vulnerable version range:
<= 2026.2.25 - Patched version:
2026.2.26(planned next release)
Impact
Under affected versions, crafted alternate paths could bypass gateway auth checks for protected plugin channel routes when plugin handlers decode/canonicalize the incoming path and then route to /api/channels/... handlers.
Fix Commit(s)
258d615c45527ffda37cecd08cd268f97461bde0
Release Process Note
patched_versions is pre-set to the planned next release (2026.2.26). After npm publish, maintainers only need to publish the advisory.
OpenClaw thanks @zpbrent for reporting.
