Users should upgrade beyond version 3.1.8 once a fixed version is released. Until then, restrict shop manager-level access to trusted users only and monitor for suspicious activity. Review plugin updates from the vendor for remediation.
Description
The Product Addons for Woocommerce – Product Options with Custom Fields WordPress plugin up to version 3.1.8 is vulnerable to a stored cross-site scripting (XSS) flaw. This vulnerability arises from insufficient input sanitization and output escaping of the 'fields[section][fields][row][col][type]' parameter. Authenticated users with shop manager-level privileges or higher can exploit this to inject malicious scripts that execute when other users view the affected pages.
