YITH WooCommerce Quick View Stored Cross-Site Scripting Vulnerability

A stored cross-site scripting vulnerability has been identified in the YITH WooCommerce Quick View plugin for WordPress, affecting all versions through 2.7.0. The vulnerability arises from inadequate input sanitization and output escaping on user-supplied attributes within the plugin's yith_quick_view shortcode. This flaw allows authenticated attackers with contributor-level access or higher to inject arbitrary web scripts into pages, which are executed when users access the affected page.

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.

Remediation

Users can update to YITH WooCommerce Quick View version 2.7.1 or a newer patched version to address this vulnerability.
