## Description

The WCFM – Frontend Manager for WooCommerce plugin for WordPress is vulnerable to unauthorized modification of data via the 'wcfm-capability' AJAX controller in all versions up to, and including, 6.8.1, due to a missing capability check: the handler only requires 'manage_woocommerce' or 'shop_staff', and the plugin itself gives the vendor role 'manage_woocommerce'. This makes it possible for authenticated attackers with vendor-level access and above to overwrite the site-wide capability settings that restrict all vendors, shop managers and shop staff.
