Reflected Cross-Site Scripting in Product Filter Widget for Elementor

Publication date: 2026-06-09

Last updated on: 2026-06-09

Assigner: Wordfence

Description
The Product Filter Widget for Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via 'args[filterFormArray]' Parameter in all versions up to, and including, 1.0.6 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 endpoint is registered via wp_ajax_nopriv_ with no nonce verification or capability check, and exploitation is delivered via a CSRF-style form auto-submission to the admin-ajax.php endpoint, requiring the attacker to trick a victim into visiting an attacker-controlled page.

Executive Summary

The Product Filter Widget for Elementor plugin for WordPress has a Reflected Cross-Site Scripting (XSS) vulnerability in the 'args[filterFormArray]' parameter in all versions up to and including 1.0.6. This occurs because the plugin does not properly sanitize input or escape output. An unauthenticated attacker can exploit this by tricking a user into clicking a malicious link, causing arbitrary web scripts to execute in the user's browser.

The vulnerability is exploitable via a CSRF-style form auto-submission to the admin-ajax.php endpoint, which is registered without nonce verification or capability checks, making it easier for attackers to deliver the exploit.

Impact Analysis

This vulnerability can allow attackers to execute arbitrary scripts in the context of the affected website when a user is tricked into clicking a malicious link. This can lead to theft of user credentials, session hijacking, defacement, or other malicious actions performed on behalf of the user.

Since the attack requires user interaction (clicking a link), it is classified with a CVSS vector indicating user interaction is needed, but it can still lead to significant confidentiality and integrity impacts.

Compliance Impact

The vulnerability allows unauthenticated attackers to inject arbitrary web scripts via reflected cross-site scripting (XSS), which can lead to unauthorized access to user data or session hijacking.

Such security weaknesses can impact compliance with standards like GDPR and HIPAA, which require protection of personal and sensitive data against unauthorized access and breaches.

Exploitation of this vulnerability could result in data exposure or manipulation, potentially violating data protection requirements and leading to non-compliance with these regulations.
