At a glance
This record tracks a medium-severity Incorrect Authorization vulnerability in the WCMultiShipping WordPress plugin, affecting versions <= 2.3.7. It carries a CVSS score of 5.3 (reachable over the network; low attack complexity). Exploitation requires no authentication. The issue is fixed in version 2.3.8; sites on affected versions should update now. Disclosed November 2023.
Vulnerability Overview
The UPS, Mondial Relay & Chronopost for WooCommerce – WCMultiShipping plugin for WordPress is vulnerable to unauthorized access of data due to an incorrect capability check on the wms_chronopost_test_credentials_ajax() function in all versions up to, and including, 2.3.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to test account credentials.
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 privileges on the target site, and no interaction from a victim user.
CWE-863: Incorrect Authorization
WCMultiShipping <= 2.3.7 carries this weakness at wms_chronopost_test_credentials_ajax(), and reaching it takes a caller who can reach the endpoint. Incorrect authorization means a permission check exists but evaluates the wrong thing, so it passes for callers it was meant to stop.
The action runs for users the code intended to exclude, with the same effect as having no check at all. For WCMultiShipping the fix is 2.3.8: builds <= 2.3.7 are affected, anything from 2.3.8 onward is not.
Remediation
Update to version 2.3.8, 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: WCMultiShipping 2.3.8 closes this, and updating the plugin is the step that ends it.
