Product Filter for WooCommerce by WBW <= 3.4.2 - Reflected Cross-Site Scripting via 'wpf_fid' Parameter
Source: CVE Program / CVE List V5
Vulnerability Description
The Product Filter for WooCommerce by WBW plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via the 'wpf_fid' parameter in all versions up to, and including, 3.4.2 due to insufficient input sanitization and output escaping.

Exploitation requires the crafted request to target a page where a filter using the vulnerable recalculation output is present.
