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

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.
