Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Keycloak's keycloak-rest-admin-ui-ext component is vulnerable in versions before 26.7.0. Bulk role-removal endpoints do not perform granular permission checks, so a delegated administrator with limited permissions can remove highly privileged roles from other users or groups. Upgrade to version 26.7.0 or later. The source gives few details on the exact preconditions for exploitation.
