ZITADEL before 3.4.14 and 4.16.2 Account Takeover via Passkey Enrollment

ZITADEL 3.x before 3.4.14 and 4.x before 4.16.2 contains an authentication bypass in the hosted Login V1 and Login V2 UIs that accepts passkey or other authenticator enrollment on identify-only login sessions, before any primary factor is verified. Unauthenticated attackers knowing only a victim's login name can register an attacker-controlled authenticator and log in as that user, bypassing existing passwords and MFA.
