Aliases CVE-2026-32036
Summary 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.
