Vulnerability in acowebs Product Addons for Woocommerce – Product Options with Custom Fields

[ Description ]Official description

The Product Addons for Woocommerce – Product Options with Custom Fields plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fields[section][fields][row][col][type]' parameter in all versions up to, and including, 3.1.8 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with shop manager-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
