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 Improper Verification of Cryptographic Signature in the backchannel logout endpoint of the keycloak-services component. An attacker can force a user to log out by sending a logout request without a cryptographic signature when an OIDC identity provider is configured to skip signature validation. This lets the attacker disrupt the user’s active session and break access to applications until the user signs in again.
