Reflected Cross-Site Scripting in Product Filter for WooCommerce

Publication date: 2026-10-31

Last updated on: 2026-10-31

Assigner: Wordfence

Description
The Product Filter for WooCommerce by WBW plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'wpf_fid' JSON Parameter in all versions up to, and including, 3.4.6 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. The vulnerability persists in versions that received the 3.4.3 patch because absint() was applied only to the getVar() read path, leaving the wpf_fid value read from the JSON-decoded filterSettings payload entirely unsanitized.

Executive Summary

This vulnerability is a Reflected Cross-Site Scripting (XSS) issue in the Product Filter for WooCommerce by WBW WordPress plugin. It affects versions up to 3.4.6 due to insufficient input sanitization and output escaping in the 'wpf_fid' JSON parameter. Attackers can inject malicious scripts into web pages that execute when a user clicks a crafted link, without needing authentication.

Impact Analysis

Unauthenticated attackers could trick users into clicking a malicious link, leading to execution of arbitrary web scripts in their browsers. This could result in session hijacking, theft of sensitive data, or defacement of web pages. The impact depends on user privileges and the nature of the injected script.

Compliance Impact

This XSS vulnerability could lead to unauthorized access to user data, potentially violating GDPR's data protection requirements or HIPAA's safeguards for protected health information. Organizations using the vulnerable plugin may face compliance risks if user data is compromised through such attacks.

Mitigation Strategies

Update the Product Filter for WooCommerce plugin by WBW to the latest version beyond 3.4.6 to ensure proper input sanitization and output escaping for the wpf_fid parameter.
