Vulnerability Description
The MyParcel plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.25.1. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to view and modify shipment options — including carrier, delivery type, package type, number of labels, weight, signature requirement, and insurance — on any arbitrary order.
