ZITADEL allows attackers to hijack accounts via passkey enrollment

CVE-2026-105212 · published 14 days ago
Summary

Versions of ZITADEL before 3.4.14 and 4.16.2 let anyone who knows a user’s login name add a fake passkey during an initial login step that has not yet verified the password. This lets the attacker log in as that user without needing the real password or multi‑factor code. Upgrade ZITADEL to the latest version or apply the vendor’s patch as soon as possible.

Original advisory text
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.
