3DescriptionGitHub Advisory
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.
AnalysisAI
Zitadel versions prior to 4.11.1 and 3.4.7 permit authenticated users to bypass email and phone verification procedures through the self-management feature, allowing them to mark contact information as verified without completing actual validation. This integrity bypass enables account compromise scenarios where attackers with valid credentials can impersonate other users or escalate privileges by falsifying verified contact details. No patch is currently available for affected deployments, though implementing action rules (v2) can mitigate the risk.
