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 Missing Authorization through the user creation path in UsersResource.create and RepresentationToModel.createGroups. An attacker can add a newly created user to groups they are not authorized to manage by submitting a user creation request with group memberships while FGAP V2 is enabled. This lets a sub-administrator who can create users place those users into restricted groups, exposing sensitive information or granting the new accounts elevated privileges.
