Advisory

Source description from Wordfence Intelligence, credited to mirphak.

The Profile Builder – User Profile & User Registration Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 3.6.4. This is due to missing nonce validation on the wppb_pbie_import() & wppb_pbie_export_our_json() functions. This makes it possible for unauthenticated attackers to import and export plugin settings via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
