01Description
The TableOn – WordPress Posts Table Filterable plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's tableon_popup_iframe_button shortcode in all versions up to, and including, 1.0.4.1 due to insufficient input sanitization and output escaping on user supplied attributes.
