Advanced Contact form 7 DB <= 2.1.1 - Missing Authorization to Authenticated (Contributor+) Information Disclosure via 'acf7db' Shortcode

The Advanced Contact form 7 DB plugin for WordPress is vulnerable to missing authorization in all versions up to, and including, 2.0.9. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with Contributor-level access and above, to read all Contact Form 7 submission data via the 'acf7db' shortcode.
