Name of the Vulnerable Software and Affected Versions
OpenClaw versions prior to 2026.8.1
Description
A resource exhaustion issue exists in the Gateway listener. Unauthenticated clients can retain response sockets by sending WebSocket upgrade requests that do not match connection semantics. By repeatedly sending these malformed upgrade requests, an attacker can exhaust listener resources and cause a denial of service, bypassing the WebSocket pre-auth connection budget.
Recommendations
Update to version 2026.8.1.
