Advisory
Source description from Wordfence Intelligence.
The Front User Submit | Front Editor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘formBuilderData’ parameter saved through the save_post_front_settings() function called via AJAX in versions up to, and including, 3.7.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
