At a glance

CVE-2025-14891 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Customer Reviews for WooCommerce WordPress plugin, affecting versions <= 5.93.1. It carries a CVSS score of 6.4 (reachable over the network; low attack complexity). Exploitation requires an authenticated account at Subscriber level or above. The issue is fixed in version 5.94.0; sites on affected versions should update now. Disclosed January 2026, reported by shark3y.

Vulnerability Overview

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'displayName' parameter in all versions up to, and including, 5.93.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with customer-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. While it is possible to invoke the AJAX action without authentication, the attacker would need to know a valid form ID, which requires them to place an order. This vulnerability can be exploited by unauthenticated attackers if guest checkout is enabled. However, the form ID still needs to be obtained through placing an order.

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-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Customer Reviews for WooCommerce <= 5.93.1 carries this weakness at displayName, and reaching it takes an account at Subscriber level or above. Cross-site scripting happens when input from a request is written into a page without being escaped for the context it lands in, so the browser parses attacker-supplied text as markup or script.

Injected script runs with the privileges of whoever views the affected page, which is how these flaws turn into administrator session theft, silent account creation or persistent backdoors in page content. For Customer Reviews for WooCommerce the fix is 5.94.0: builds <= 5.93.1 are affected, anything from 5.94.0 onward is not.

Remediation

Update to version 5.94.0, 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 5.94.0 closes this, and updating the plugin is the step that ends it.
