Official description
OpenClaw is a personal AI assistant. Prior to 2026.3.11, browser-originated WebSocket connections could bypass origin validation when gateway.auth.mode was set to trusted-proxy and the request arrived with proxy headers. A page served from an untrusted origin could connect through a trusted reverse proxy, inherit proxy-authenticated identity, and establish a privileged operator session. This vulnerability is fixed in 2026.3.11.
