A flaw was found in the Admin REST API of Keycloak, an open-source identity and access management solution. The issue occurs in the group-membership endpoints where the system fails to check if a group grants administrative privileges before allowing a user to be added. This allows a delegated administrator with limited permissions to add themselves to a high-privilege group, potentially gaining full control over the entire realm.
