## Description

The BuddyForms plugin for WordPress is vulnerable to Information Exposure in versions 2.5.9 up to, and including, 2.10.0. When a form with AJAX submission disabled fails validation, the plugin stores the submitted values under a name built only from the form slug and the entry ID, and loads them into any request that carries those two values, without verifying the nonce. Because logged-out visitors of a form share the same entry ID, this makes it possible for unauthenticated attackers to view the values another visitor entered in a failed submission of such a form.
