CVE-2026-56666

Descrição

ZITADEL is an open source identity management platform. Prior to 4.15.3, ZITADEL-s external identity provider handler checks that the local user-s email is verified but does not verify that the external IdP confirmed ownership of the same email before auto-linking by email, allowing a permissive provider account with a victim email address to be linked to the victim-s local account. This issue is fixed in version 4.15.3.
