At a glance

CVE-2024-1756 is a medium-severity Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the WooCommerce Customers Manager WordPress plugin, affecting versions <= 29.7. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The root cause is a missing authorization check on a reachable function. The issue is fixed in version 29.8; sites on affected versions should update now. Disclosed April 2024, reported by Erwan LR.

Vulnerability Overview

The WooCommerce Customers Manager plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the wccm_get_customers_list AJAX action in all versions up to, and including, 29.7. This makes it possible for authenticated attackers, with subscriber-level access and above, to retrieve a list of customers and their data.

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-200: Exposure of Sensitive Information to an Unauthorized Actor

Reaching this weakness in WooCommerce Customers Manager <= 29.7 takes a caller who can reach the endpoint. Sensitive information exposure means data the application intended to keep internal is returned to a caller who should not be able to see it.

The disclosed data — credentials, tokens, customer records or internal paths — is usually worth more as material for a follow-up attack than as an end in itself. For WooCommerce Customers Manager the fix is 29.8: builds <= 29.7 are affected, anything from 29.8 onward is not.

Remediation

Update to version 29.8, or a newer patched version

How does WordSec protect against this?

The fix is the thing that ends this: WooCommerce Customers Manager 29.8 closes this, and updating the plugin is the step that ends it.
