GHSA-X6M6-7QG7-7R64
Vulnerability from github – Published: 2026-09-25 09:31 – Updated: 2026-09-25 09:31A 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.
