- Summary
- This vulnerability allows attackers with user-write permission in one organization to obtain an enrollment code for a user in another organization, potentially leading to account takeover.
- Exploitability
- Exploitation is relatively straightforward given the required user-write permission in one organization, and the attacker can then obtain an enrollment code for a user in another organization.
- Blast radius
- If exploited, the impact is high as attackers can take over accounts in different organizations, leading to potential data breaches and unauthorized access.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to ZITADEL 3.4.15 or 4.17.1 or later.

NVD description
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.
