Dynamic AJAX Product Filters for WooCommerce Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the Dynamic AJAX Product Filters for WooCommerce plugin, affecting all versions through 1.3.7. The issue arises from inadequate input sanitization and output escaping, allowing authenticated attackers with Contributor-level access or higher to inject arbitrary scripts. These scripts are executed when users access the affected pages.

Impact

Exploitation of this vulnerability allows for stored cross-site scripting, where injected scripts are executed in the context of the user viewing the page.

Reproduction

To reproduce this vulnerability, an authenticated user with Contributor-level access can inject scripts through the 'name' parameter. This can be done by accessing the filter management options in the WordPress admin dashboard, where the 'name' parameter can be modified. Once the script is injected, it will be executed when the page is accessed by any user.

Remediation

Users are advised to update the Dynamic AJAX Product Filters for WooCommerce plugin to version 1.3.8 or later, where this vulnerability has been patched.
