Does this matter?

Lower severity and a low EPSS score (0.60%). Track it; it rarely justifies an emergency change on its own.

Description

A flaw was found in Keycloak, where it does not correctly validate its client step-up authentication in org.keycloak.authentication. This flaw allows a remote user authenticated with a password to register a false second authentication factor along with an existing one and bypass authentication.
