Description
The Themify Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'visible' option of the Slider and Gallery Slider modules, including the slider shortcode attribute, in all versions up to, and including, 7.8.2. This is due to insufficient input sanitization and output escaping of the value echoed into the data-visible HTML attribute. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
