What the vulnerability does
01Description
The Additional Order Filters for WooCommerce plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'shipping_method_filter' parameter in all versions up to, and including, 1.21 due to insufficient input sanitization and output escaping.
