There is no fixed version for org.keycloak:keycloak-services.
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 Google token exchange flow in the Google Identity Provider token exchange process. An attacker can gain access to a Keycloak realm by supplying a valid Google token from a non-approved Google Workspace domain and exchanging it for a Keycloak token. The issue affects deployments that rely on Google domain restrictions to limit which accounts may sign in, allowing users from disallowed domains to authenticate successfully.
