01Description
The App Landing Template Blocks for WPBakery (Visual Composer) Page Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'atvc_video_play' shortcode in all versions up to, and including, 2.0.2 due to insufficient input sanitization and output escaping on user supplied attributes.
