CVE-2026-96448 vulnerability in Red Hat Products
Published on September 25, 2026
Keycloak-services: keycloak-services: fgap v2 composite-blind role mapping allows privilege escalation
A flaw was found in the Fine-Grained Admin Permissions (FGAP v2) feature of Keycloak, an identity and access management solution. The issue occurs when the system checks if a delegated administrator has permission to assign a specific role to a user. Because the check does not look inside composite roles to see what other permissions they contain, an administrator with limited rights can assign a role that secretly includes full administrative control. This allows the attacker to gain complete management access over the entire realm.
