NVD Description

Note: Versions mentioned in the description apply only to the upstream keycloak-doc package and not the keycloak-doc package as distributed by Minimos. See How to fix? for Minimos:latest relevant fixed versions and status.

A flaw was found in Keycloak’s WebAuthn registration component. This vulnerability allows an attacker to bypass the configured attestation policy and register untrusted or forged authenticators via submission of an attestation object with fmt: "none", even when the realm is configured to require direct attestation. This can lead to weakened authentication integrity and unauthorized authenticator registration.
