Keycloak-services: keycloak-services: client policy source-group condition bypass via duplicate group name matching
Summary
A flaw was found in the client policy enforcement mechanism of Keycloak. The issue occurs when the system checks group membership by name instead of a unique identifier. An attacker with client management privileges could bypass security policies by joining a group with a matching name in a different part of the group hierarchy, potentially allowing them to register or update clients without following required security hardening profiles. Affected product named by the advisory: Red Hat Build of Keycloak.
