  - A flaw was found in the ClientResource component of Keycloak's admin services when Fine-Grained Admin
    Permissions (FGAP) v2 is enabled. This issue allows a delegated administrator, who should only have
    limited control over specific clients, to attach or remove hidden client scopes that they are not
    authorized to see or manage. As a result, an attacker could inject unauthorized data or permissions into
    the security tokens issued to end-users, potentially tricking other applications into granting higher
    levels of access than intended. (CVE-2026-14614)
