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 Input Validation. Depending on the webserver configuration, a malicious user can supply an expired certificate and it would be accepted by Keycloak direct-grant authenticator. This is because Keycloak does not trigger the appropriate timestamp validation.
