User Registration Using Contact Form 7 <= 2.5 - Authenticated (Subscriber+) Information Exposure

The User Registration Using Contact Form 7 plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'get_cf7_form_data' function in all versions up to, and including, 2.5. This makes it possible for unauthenticated attackers to retrieve form settings which includes Facebook app secrets.
