Summary

A flaw was found in the admin-ui-ext component of Keycloak, which provides extended administrative user interface capabilities. The issue occurs because certain bulk role-removal endpoints fail to perform granular permission checks when deleting role mappings. This allows a delegated administrator with limited permissions to remove highly privileged roles from other users or groups, potentially disrupting administrative access control.

Affected packages

Ecosystem	Package	Affected versions	Fixed versions
Maven	org.keycloak:keycloak-rest-admin-ui-ext	—	26.7.0

Remediation: Upgrade to 26.7.0 or later.
