- Description
- OpenClaw versions prior to 2026.2.25 contain an authentication hardening gap in browser-origin WebSocket clients that allows attackers to bypass origin checks and auth throttling on loopback deployments. An attacker can trick a user into opening a malicious webpage and perform password brute-force attacks against the gateway to establish an authenticated operator session and invoke control-plane methods.
