Order Tracking < 3.6.2 - Unauthenticated Customer and Sales Rep Order History Disclosure via IDOR

The Order Tracking WordPress plugin before 3.6.2 does not verify that a visitor owns the customer or sales representative account whose orders they request, and the account numbers default to sequential values, allowing unauthenticated users to retrieve the order history of every customer and sales representative, including order contact email addresses in some versions.
