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 TokenManager component in the identity management service. An attacker can continue using previously issued tokens by presenting them after an administrator applies a client-specific “not-before” revocation policy while the realm already has an older non-zero revocation policy in place. This leaves revoked tokens valid for refreshing sessions and accessing user information, so administrators cannot reliably invalidate a client’s existing tokens.
