Vulnerability details
The vulnerability allows a low-privileged remote attacker to bypass OpenClaw's cross-context message mutation policy and remove pins from another Feishu group.
The vulnerability exists due to missing cross-context target validation in the Feishu unpin action when tools.message.crossContext.allowWithinProvider is disabled. A low-privileged remote attacker can submit an unpin request as an admitted sender targeting another group that both the sender and configured account are authorized to access, removing a pin despite the policy.
