Description

The WCFM – Frontend Manager for WooCommerce along with Bookings Subscription Listings Compatible plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.7.25 via the 'wcfm_delete_wcfm_customer' due to missing validation on the 'customerid' user controlled key. This makes it possible for authenticated attackers, with Vendor-level access and above, to delete arbitrary users, including Administrators.
