ZITADEL before 3.4.15 and 4.17.1 Cross-Organization Account Takeover via Passkey Enrollment
ZITADEL 3.x before 3.4.15 and 4.x before 4.17.1 contains an improper authorization vulnerability: when issuing passkey or passwordless enrollment codes, it checks only the organization in the x-zitadel-orgid header, not the target user's organization. Attackers with user-write permission in one organization can obtain an enrollment code for a user in another organization on the same instance and register their own authenticator to take over that account.
