[MAVEN:GHSA-4F53-XH3V-G8X4] Keycloak secondary factor bypass in step-up authentication

Severity Moderate

Affected Packages 2

Fixed Packages 2

CVEs 1

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.
