Description

The Master Slider – Responsive Touch Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's 'ms_slide_info' shortcode in all versions up to, and including, 3.9.9 due to insufficient input sanitization and output escaping on user supplied 'tag_name' attribute.
