The manipulation of the argument tpro_client_name with an unknown input leads to a cross site scripting vulnerability. Using CWE to declare the problem leads to CWE-79.

CVE summarizes:

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_name' 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 publish the submitted testimonial, trigger the Show Preview AJAX handler, and save an Update, which canonicalizes and persists the attacker-controlled payload as the Manage View title — matching the plugin's standard moderation workflow. Successful exploitation additionally requires an action by an administrator — the attacker cannot trigger the vulnerability on their own.

The advisory is available at wordfence.com. This vulnerability is handled as CVE-2026-120509 since 11/02/2026. The exploitation is known to be easy. The attack may be launched remotely. Additional levels of successful authentication are necessary for exploitation. Successful exploitation requires user interaction by the victim. Technical details are known, but there is no available exploit. This vulnerability is assigned to T1059.007 by the MITRE ATT&CK project.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
