At a glance

CVE-2022-40194 is a medium-severity Improper Authorization vulnerability in the Customer Reviews for WooCommerce WordPress plugin, affecting versions <= 5.3.5. It carries a CVSS score of 4.3 (reachable over the network; low attack complexity). The issue is fixed in version 5.3.6; sites on affected versions should update now. Disclosed September 2022, reported by Muhammad Daffa.

Vulnerability Overview

The Customer Reviews for WooCommerce plugin contains several AJAX actions that are not protected by capability or nonce checks in versions up to, and including, 5.3.5. This allows authenticated users, such as subscribers, to perform actions that should be restricted to administrators, such as exporting sensitive data including unpublished reviews.

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-285: Improper Authorization

Reaching this weakness in Customer Reviews for WooCommerce <= 5.3.5 takes a caller who can reach the endpoint. Improper authorization means a permission check exists but does not cover the case being exercised, so a caller who is allowed to do one thing is allowed to do a neighbouring thing as well.

A lower-privileged account performs an action reserved for a higher one, which on a multi-author or membership site means an ordinary user reaching administrative behaviour. For Customer Reviews for WooCommerce the fix is 5.3.6: builds <= 5.3.5 are affected, anything from 5.3.6 onward is not.

Remediation

Update to version 5.3.6, 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 5.3.6 closes this, and updating the plugin is the step that ends it.
