## Affected

- wpclever WPC Badge Management for WooCommerce: through 3.1.6

## 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 on user supplied attributes. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
