How to fix?

Upgrade org.keycloak:keycloak-services to version 24.0.3 or higher.

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 Enforcement of a Single, Unique Action allowing an attacker to bypass brute force protection mechanisms by initiating multiple login requests simultaneously, thus exceeding the configured limits for failed attempts, before the system locks them out. This timing loophole enables attackers to make more guesses at passwords than intended, potentially compromising account security on affected systems.

Note: This is only exploitable if Keycloak is configured with Brute Force Protection.
