In Zulip Server versions through 12.1, GenericOpenIdConnectBackend matches the identity provider email claim to an active account&#39;s delivery_email without rejecting an explicitly false email_verified claim. If a configured identity provider returns an email address that the authenticating user does not control together with email_verified=false, Zulip can log the user into the existing account for that address. Exploitation requires a misconfigured trusted identity provider, and deployments whose authoritative identity provider only emits email addresses controlled by the authenticating user are not affected. This issue is fixed in version 12.2.</p> <p>Zulip is an open-source team collaboration tool.
