Vulnerability Overview
The WooCommerce Multiple Customer Addresses & Shipping plugin for WordPress is vulnerable to Missing Authorization in versions up to, and including, 21.6. This is due to missing protections on the plugin's administrative functions. This makes it possible for subscriber-level attackers to create, delete, view, and update addresses of other users.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.
CWE-639: Authorization Bypass Through User-Controlled Key
Reaching this weakness in WooCommerce Multiple Customer Addresses & Shipping < 21.7 takes an account at Subscriber level or above. Authorization bypass through a user-controlled key, often called insecure direct object reference, means the application looks up a record by an identifier from the request without checking that the caller owns it.
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 WooCommerce Multiple Customer Addresses & Shipping the fix is 21.7: builds < 21.7 are affected, anything from 21.7 onward is not.
Remediation
Update to version 21.7, or a newer patched version
How does WordSec protect against this?
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: WooCommerce Multiple Customer Addresses & Shipping 21.7 closes this, and updating the plugin is the step that ends it.
