Vulnerability details
The vulnerability allows a remote user to bypass owner-only restrictions and access tools backed by server credentials and capabilities reserved for owners.
The vulnerability exists due to incorrect authorization in OpenClaw's skill tool dispatch when handling skill-backed commands without carrying the sender's owner status or applying the owner-only tool filter. A remote user can invoke an allowlisted skill-backed command as a non-owner to access owner-only tools exposed by the installed skill.
Practical impact depends on which owner-only command tool the installed skill exposes.
