Sources and claim methodology

Upstream source description

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.
