The Funnel Builder for WordPress by FunnelKit – Customize WooCommerce Checkout Pages, Create Sales Funnels, Order Bumps & One Click Upsells plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘mimes’ parameter in all versions up to, and including, 3.3.1 due to insufficient input sanitization and output escaping.
