Official description

A flaw was found in the Admin REST API of Keycloak, an identity and access management solution. The endpoints used to retrieve groups associated with a specific role do not properly check for individual group visibility permissions. This allows a delegated administrator with basic search privileges to view detailed information about all groups assigned to a role, bypassing intended security restrictions that should limit their view to specific groups.
