CVE-2026-32031
OpenClaw: /api/channels gateway-auth boundary bypass via path canonicalization mismatch
Description
### Summary Gateway auth for plugin channel endpoints can be bypassed when path canonicalization differs between the gateway guard and plugin handler routing. ### Details On affected versions, `server-http` only applies gateway auth when raw `requestPath` matches exactly: - `/api/channels` - `/api/channels/*` If a plugin handler canonicalizes path input (for example `decodeURIComponent(pathname).toLowerCase()`), requests like: - `/API/channels/nostr/default/profile` - `/api/channels%2Fnostr%2Fdefault%2Fprofile` can be interpreted as `/api/channels/*` by the plugin, while the gateway auth guard is skipped. ### Impact Authentication boundary bypass for plugin channel HTTP routes under canonicalization mismatch conditions. Unauthorized callers may access plugin channel APIs that are expected to require gateway auth. CWE: CWE-288 (Authentication Bypass Using an Alternate Path or Channel) CVSS: `CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:N` (Base 5.3, Moderate)
