CVE-2026-27946 Details
Description
ZITADEL is an open source identity management platform. Prior to versions 4.11.1 and 3.4.7, a vulnerability in Zitadel's self-management capability allowed users to mark their email and phone as verified without going through an actual verification process. The patch in versions 4.11.1 and 3.4.7 resolves the issue by requiring the correct permission in case the verification flag is provided and only allows self-management of the email address and/or phone number itself. If an upgrade is not possible, an action (v2) could be used to prevent setting the verification flag on the own user.
A vulnerability exists in ZITADEL's self-management feature, allowing users to falsely verify their email and phone numbers without undergoing the actual verification process. This issue is present in ZITADEL versions 4.0.0 through 4.11.0, 3.0.0 through 3.4.6, and 2.43.0 through 2.71.19. The flaw arises from an inadequate permission check in the API that manages user data, enabling users to claim ownership of contact information they do not control, potentially circumventing email-based security measures.
Users can upgrade to ZITADEL versions 4.11.1, 3.4.7, or 2.71.19 to address this vulnerability. If an upgrade is not feasible, an action (v2) can be used to prevent setting the verification flag on one's own user account.
