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 Validation of Consistency within Input in the identity provider update flow for OIDC identity providers. An attacker can capture the existing client secret by sending an update as a delegated administrator that reuses the masked client secret sentinel value while changing security-sensitive settings such as the token URL.
The vulnerable code path manages identity provider configuration updates in keycloak-services, and it accepts the update without forcing the secret to be revalidated against the changed endpoint. This lets the attacker redirect secret-bearing requests to an endpoint they control and expose the real client secret, breaking the confidentiality of the identity provider credentials.
