## Description

The Everest Forms plugin for WordPress is vulnerable to Sensitive Information Exposure via the email preview feature in all versions up to, and including, 3.6.3. This is due to a missing capability check when the email preview template loads a form chosen by the user. This makes it possible for authenticated attackers, with subscriber-level access and above, to view the email notification message content of any form through the 'evf_email_preview' and 'form_id' parameters.
