Vulnerability Overview
The Testimonial Carousel For Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via multiple parameters in versions less than, or equal to, 11.6.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
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')
Reaching this weakness in Testimonial Carousel For Elementor <= 11.6.2 takes an account at Contributor 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 Testimonial Carousel For Elementor the fix is 11.7.0: builds <= 11.6.2 are affected, anything from 11.7.0 onward is not.
Remediation
Update to version 11.7.0, or a newer patched version
How does WordSec protect against this?
An attacker needs Contributor 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: Testimonial Carousel For Elementor 11.7.0 closes this, and updating the plugin is the step that ends it.
