EntreBase Advisory: The MDTF – Meta Data and Taxonomies Filter plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin\’s \’mdf_results_by_ajax\’ shortcode in all versions up to, and including, 1.3.3.6 due to insufficient input sanitization and output escaping on user supplied attributes.
