Does this matter?

Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.

Description

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.
