Keycloak Admin UI REST Extensions: bulk role-removal endpoints fail to perform granular permission checks
Quick fix
GHSA-6w3v-mcfh-m3q7 — org.keycloak:keycloak-rest-admin-ui-ext: upgrade to the fixed version with the command below.
# pom.xml: bump <version>26.7.0</version> for org.keycloak:keycloak-rest-admin-ui-extDetails
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.
