CVE-2026-11591 is a medium-severity Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in the Widgets for Google Reviews WordPress plugin, affecting versions <= 13.3. It carries a CVSS score of 4.4 (reachable over the network). Exploitation requires an authenticated account at Editor level or above.

Vulnerability Overview
The Widgets for Google Reviews plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 13.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with editor-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, and no interaction from a victim user.
CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Reaching this weakness in Widgets for Google Reviews <= 13.3 takes an account at Editor 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 Widgets for Google Reviews the fix is 13.3.1: builds <= 13.3 are affected, anything from 13.3.1 onward is not.
Remediation
Update to version 13.3.1, or a newer patched version
How does WordSec protect against this?
An attacker needs Editor 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: Widgets for Google Reviews 13.3.1 closes this, and updating the plugin is the step that ends it.
