Technical description
The WPC Badge Management for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'text' attribute of the `wpcbm_best_seller` shortcode in all versions up to, and including, 3.1.6 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.
