ZITADEL Users Can Self-Verify Email/Phone via API
CVE-2026-54693
Description
ZITADEL is an open source identity management platform. From 2.43.0 through 2.71.19, from 3.0.0 until 3.4.11, and from 4.0.0 until 4.15.1, the email and phone self-management API paths in internal/command/user_v2_email.go, internal/command/user_v2_phone.go, and internal/command/user_v2_human.go allowed users to request returned verification codes without the required permission, allowing users to claim ownership of email addresses or phone numbers they do not control and bypass email-based or phone-based security policies. This issue is fixed in versions 3.4.11 and 4.15.1.
