Vulnerability details
The vulnerability allows a low-privileged remote attacker to bypass sender tool restrictions and create persistent scheduled work.
The vulnerability exists due to incorrect authorization in OpenClaw's session-memory filename generation, whose helper exposes tools removed by the originating sender's policy when the feature is enabled for agents reachable by lower-trust senders. A low-privileged remote attacker can inject instructions that invoke those tools if the model follows them.
