Vulnerability details
The vulnerability allows a low-privileged remote attacker who is an unlisted Microsoft Teams member to trigger OpenClaw's configured agent despite administrator-defined group restrictions.
The vulnerability exists due to Teams message admission failing to reject denied results from missing or unsupported access groups when groupPolicy is set to allowlist. A low-privileged remote attacker can send a Teams message that bypasses the configured group boundary and invokes the agent.
