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 OIDC token introspection endpoint in the keycloak-services component. An attacker can access sensitive token claims by sending an introspection request for a token issued to a different audience from a confidential client configured to receive signed JWT introspection responses. The endpoint marks the token inactive for that client, but it still returns the token’s full claims inside the signed JWT response. This lets an unauthorized client recover audience-restricted token data that should not be exposed.
