Summary

The Flatsome theme for WordPress is vulnerable to Stored Cross-Site Scripting via the UX Countdown, Video Button, UX Video, UX Slider, UX Sidebar, and UX Payment Icons shortcodes in all versions up to, and including, 3.18.7 due to insufficient input sanitization and output escaping on user supplied attributes.
