CVE-2024-3869 is a medium-severity Missing Authorization vulnerability in the Customer Reviews for WooCommerce WordPress plugin, affecting versions <= 5.46.0. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above.

Vulnerability Overview

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the 'woocommerce_json_search_coupons' function . This makes it possible for attackers with subscriber level access to view coupon codes.

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-862: Missing Authorization

Customer Reviews for WooCommerce <= 5.46.0 carries this weakness at woocommerce_json_search_coupons, and reaching it takes an account at Subscriber level or above. A missing authorization check means a function is reachable by anyone who can reach the endpoint, because the code never asks whether the caller is allowed to perform the action.

Any user who can reach the endpoint gets to run an action reserved for higher-privileged roles, from reading protected data to changing settings or content. For Customer Reviews for WooCommerce the fix is 5.47.0: builds <= 5.46.0 are affected, anything from 5.47.0 onward is not.

Remediation

Update to version 5.47.0, 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: Customer Reviews for WooCommerce 5.47.0 closes this, and updating the plugin is the step that ends it.
