No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

OpenClaw before 2026.4.25 contains an input validation vulnerability in tool group policy callers that accept unvalidated group IDs. Attackers who can supply a group ID to the policy resolver could trigger incorrect group-policy decisions for tool invocations, potentially bypassing intended access controls.
