    Summary: Keycloak secondary factor bypass in step-up authentication

    Details: Keycloak does not correctly validate its client step-up authentication. A password-authed attacker could use this flaw to register a false second auth factor, alongside the existing one, to a targeted account. The second factor then permits step-up authentication.
