An authenticated Control Panel user could use an endpoint intended for the user creation wizard to determine if a given email address belonged to an existing user, without having permission to view users, though the endpoint only exposed user existence and not any other user data. Vendor/CNA’s CVSS 3.1 assessment (base score 4.3/10) rates confidentiality impact as low; integrity and availability impact as none.
