Overview
org.keycloak:keycloak-server-spi-private is an open source identity and access management solution for modern applications and services.
Affected versions of this package are vulnerable to Missing Authorization in the RoleContainerResource admin REST composite-role endpoints. A delegated administrator can remove child roles from built-in admin roles by sending name-based composite-role requests against the realm admin API, bypassing the per-role checks that should gate those updates. This can strip essential permissions such as manage-users, manage-clients, or impersonation from administrative roles, disrupting or degrading administrative access within the realm.
