Official description

OpenClaw before 2026.4.25 contains a privilege escalation vulnerability in internal and webchat command authentication that allows senders to inherit wildcard ownerAllowFrom state across channel boundaries. Attackers can exploit this by sending commands on affected internal or webchat paths to execute owner-style command behavior outside intended channel scope, potentially bypassing access controls.
