CVE-2025-8073 in Dynamic AJAX Product Filters for WooCommerce Plugin
Summary
by MITRE • 08/28/2025
The Dynamic AJAX Product Filters for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ‘name’ parameter in all versions up to, and including, 1.3.7 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

The Dynamic AJAX Product Filters for WooCommerce plugin presents a critical stored cross-site scripting vulnerability that affects all versions through 1.3.7. This vulnerability stems from inadequate input validation and output escaping mechanisms within the plugin's handling of the 'name' parameter. The flaw specifically targets the plugin's ajax filtering functionality where user-supplied data is not properly sanitized before being stored in the database and subsequently rendered in web pages. Attackers with contributor-level access or higher can exploit this weakness to inject malicious scripts that persist in the plugin's data storage, making the vulnerability particularly dangerous as it can affect any user who accesses pages containing the injected content.
The technical exploitation of this vulnerability follows a standard stored XSS attack pattern where malicious input is first accepted and stored without proper sanitization. When the 'name' parameter contains malicious script code, it gets saved to the database and executed whenever the filtered results are displayed to other users. This type of vulnerability falls under CWE-79 which specifically addresses cross-site scripting flaws in web applications. The vulnerability's impact is amplified by the plugin's widespread use within the WooCommerce ecosystem, where it serves as a core filtering mechanism for product displays. The stored nature of the vulnerability means that the malicious scripts remain active until manually removed from the database, creating a persistent threat vector that can affect multiple users over extended periods.
The operational impact of CVE-2025-8073 extends beyond simple script execution as it can enable attackers to perform various malicious activities including session hijacking, data theft, and redirection to malicious sites. Contributors and higher privilege users who typically have access to product management features can leverage this vulnerability to inject scripts that could steal administrator credentials or manipulate product listings. The vulnerability aligns with ATT&CK technique T1566.001 which covers the use of malicious web content to compromise systems. Given that WooCommerce is one of the most popular e-commerce platforms, the potential for widespread exploitation exists, particularly in environments where multiple users with contributor privileges have access to the site administration. The vulnerability's persistence means that even if an administrator discovers and removes the malicious content, the scripts may have already executed against other users, potentially leading to credential theft or other security breaches.
Mitigation strategies for this vulnerability require immediate patching of the plugin to version 1.3.8 or later, which should include proper input sanitization and output escaping mechanisms. Administrators should implement additional security measures such as restricting contributor-level access to sensitive plugin functionalities and monitoring for unusual data modifications. The implementation of Content Security Policy headers can provide additional defense-in-depth against script execution, while regular security audits of plugin installations can help identify similar vulnerabilities. Organizations should also consider implementing web application firewalls to detect and block malicious script injection attempts. The vulnerability demonstrates the critical importance of proper input validation and output escaping in web applications, particularly those handling user-generated content in e-commerce environments where data integrity and user security are paramount.
