The Everest Forms – Contact Form, Payment Form, Quiz, Survey & Custom Form Builder plugin for WordPress is vulnerable to unauthorized email sending due to a missing capability check on the send_test_email() function in all versions up to, and including, 3.4.7. This makes it possible for authenticated attackers, with Subscriber-level access and above, to send test emails to arbitrary addresses from the server.
