Dataverse Integration < 2.91 - Contributor+ Server-Side Template Injection (SSTI) to Information Disclosure

The DataPress (Dataverse Integration) WordPress plugin before 2.91 does not properly restrict access to its template rendering feature and exposes the viewing user's data to it, allowing users with a role as low as Contributor to disclose sensitive information, such as the session cookies of higher privileged users who view the affected content.
