At a glance

CVE-2023-0080 is a high-severity Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Customer Reviews for WooCommerce WordPress plugin, affecting versions <= 5.15.0. It carries a CVSS score of 8.1 (reachable over the network; low attack complexity; high confidentiality, integrity impact). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 5.16.0; sites on affected versions should update now. Disclosed January 2023, reported by István Márton.

Vulnerability Overview

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Directory Traversal in versions up to, and including, 5.15.0 via a shortcode attribute. This allows subscriber-level attackers to read the contents of arbitrary files on the server, which can contain sensitive information.

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. A successful exploit has high impact on confidentiality, integrity.

CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Reaching this weakness in Customer Reviews for WooCommerce <= 5.15.0 takes an account at Subscriber level or above. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.

Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For Customer Reviews for WooCommerce the fix is 5.16.0: builds <= 5.15.0 are affected, anything from 5.16.0 onward is not.

Remediation

Update to version 5.16.0, or a newer patched version

How does WordSec protect against this?

An attacker needs Subscriber access first, so the firewall sees the attempt as traffic from a logged-in account: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Customer Reviews for WooCommerce 5.16.0 closes this, and updating the plugin is the step that ends it.
