CVE-2026-11986

Name of the Vulnerable Software and Affected Versions Keycloak (affected versions not specified)

Description A flaw exists in the admin-ui-ext component, which extends the administrative user interface. The issue stems from a failure to perform granular permission checks within bulk role-removal endpoints when deleting role mappings. Consequently, a delegated administrator with restricted permissions can remove highly privileged roles from other users or groups, which may disrupt administrative access control.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
