CWE-639: Authorization Bypass Through User-Controlled Key

Changing a number in the request is enough to read or modify other users' records, which on commerce and membership sites means customer data. For Colissimo shipping methods for WooCommerce the fix is 3.0.0: builds <= 2.10.0 are affected, anything from 3.0.0 onward is not.

How WordSec helps
Because it turns on account access, WordSec's login security is the relevant layer: role-based two-factor, captcha and brute-force limits raise the cost of getting the account this needs. None of that substitutes for the fix: Colissimo shipping methods for WooCommerce 3.0.0 closes this, and updating the plugin is the step that ends it.
