At a glance

CVE-2026-120683 is a medium-severity Improper Neutralization of Input During Web Page Generation vulnerability in the Real Testimonials WordPress plugin, affecting versions <= 4.1.0. It carries a CVSS score of 5.4 (reachable over the network). Exploitation requires no authentication. The issue is fixed in version 4.1.1; sites on affected versions should update now. Disclosed November 2026, reported by Mohamed Amgad Khater (mamgad).

Vulnerability Overview

The Real Testimonials – Testimonial Slider, Collect Customer Reviews and Video Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'tpro_client_testimonial' parameter in all versions up to, and including, 4.1.0 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful exploitation requires an administrator to approve the pending testimonial through standard moderation and the target page to load the WordPress Interactivity runtime (e.g. a theme or block that enqueues @wordpress/interactivity).

Technical Analysis

The vector marks this flaw as remotely reachable over the network, and no privileges on the target site, and no interaction from a victim user.

CWE-79: Improper Neutralization of Input During Web Page Generation

Real Testimonials <= 4.1.0 carries this weakness at tpro_client_testimonial, and reaching it takes no account at all. 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 Real Testimonials the fix is 4.1.1: builds <= 4.1.0 are affected, anything from 4.1.1 onward is not.

Remediation

Update to version 4.1.1, or a newer patched version

How does WordSec protect against this?

Requests carrying this pattern arrive without a session, so nothing upstream of the firewall gets a chance to reject them: WordSec's web application firewall inspects request payloads before WordPress loads them. None of that substitutes for the fix: Real Testimonials 4.1.1 closes this, and updating the plugin is the step that ends it.
