## Description

The PeproDev Ultimate Profile Solutions plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 8.3.0, due to insufficient authorization in the dashboard's WooCommerce order view (classic and modern templates). These templates grant access to an order whenever the current user's account email matches the order's billing email, and the account email can be changed from the profile without confirmation. Older releases had no ownership check on this view at all. This makes it possible for authenticated attackers, with Subscriber-level access and above, to view other customers' orders, including guest orders, exposing purchased items, billing and shipping addresses, phone numbers, email addresses and totals.
