A fix was pushed into the master branch but not yet published.
Overview
org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Information Exposure due to insufficient group-permission filtering in RealmAdminResource.getRealm(), RealmAdminResource.getDefaultGroups(), and RealmsAdminResource.toRealmRep() in the admin REST API. A delegated administrator can enumerate hidden default groups by requesting the realm representation or the default-groups endpoint after being granted realm-view permissions but denied per-group view access.
This exposes the names, paths, and identifiers of default groups that should remain hidden, revealing internal organizational structure to users who do not have permission to view those groups.
Notes
- FGAP v2 must be enabled for the hidden-default-group checks to matter; the issue is in the delegated-admin/admin-permissions path that evaluates realm and group view rights separately.
- The disclosure also affects the realm listing returned by
admin/realmsviaRealmsAdminResource.toRealmRep(), not just the dedicateddefault-groupsendpoint.
