The Booster for WooCommerce for WordPress is a plugin that, until version 7.1.1, had a security flaw that could allow unauthorized access to sensitive information. This flaw was located in the ‘wcj_get_option’ shortcode. With this flaw, anyone who had an account on the website with subscriber-level capabilities or higher could view the site’s sensitive information without authorization. Version 7.1.1 and higher have fixed this security issue.
