Vulnerability Title
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. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Exploitation requires the crafted request to target a page where a filter using the vulnerable recalculation output is present.
