Deeper analysis

The WooCommerce Multiple Customer Addresses & Shipping WordPress plugin before version 21.7 is affected by an authorization bypass vulnerability tracked as CWE-639. The plugin does not verify ownership of address records when performing add, update, retrieve, delete, or duplicate operations, allowing requests to succeed regardless of whether the acting user owns the data or holds high privileges.

Any authenticated user, including those assigned only subscriber rights, can exploit the flaw over the network to access, modify, duplicate, or remove address information belonging to other accounts. Successful exploitation yields full control over the targeted address data and carries a CVSS 3.1 score of 8.8.

Public advisories published via WPScan detail the affected plugin versions and recommend upgrading to 21.7 or later to correct the missing authorization checks. The associated EPSS score has remained low, with a current value of 0.0760 and a peak of 0.0880.
