Product Filter Widget for Elementor Reflected Cross-Site Scripting Vulnerability

A reflected cross-site scripting vulnerability has been identified in the Product Filter Widget for Elementor plugin for WordPress, affecting all versions through 1.0.6. The issue arises from inadequate input sanitization and output escaping, allowing unauthenticated attackers to inject arbitrary web scripts. These scripts could execute if a user is tricked into clicking a link. The vulnerability is delivered via a CSRF-style form auto-submission to the admin-ajax.php endpoint, exploiting an absence of nonce verification or capability checks. The 'args[filterFormArray]' parameter is the vector for this attack.

Impact

Exploitation of this vulnerability allows for reflected cross-site scripting, where an attacker can inject scripts that are executed in the context of the user.
