MediumCVSS 6.1Exploitation Probability (EPSS)
Low risk18th percentile - higher than 18% of all known CVEs
Summary
The Product Filter Widget for Elementor plugin for WordPress is vulnerable to Reflected Cross-Site Scripting (XSS) via the 'args[filterFormArray]' parameter in all versions up to and including 1.0.6 due to insufficient input sanitization and output escaping.
Risk Assessment
Unauthenticated attackers can inject arbitrary web scripts, potentially leading to session hijacking or data theft. The risk increases when users are tricked into performing actions on a malicious page.
Recommendation
It is recommended to update the plugin to the latest version to mitigate this vulnerability. Additionally, implementing extra security measures such as nonce verification and capability checks is advisable.
Original NVD description (English source)
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.
