The Strong Testimonials plugin for WordPress suffers from a stored XSS vulnerability (CWE-79) due to improper neutralization of input during web page generation. This allows authenticated users with Author or higher privileges to inject arbitrary scripts via Testimonial Custom Fields. These scripts execute in the context of users viewing the injected pages, potentially leading to information disclosure or session hijacking. The vulnerability affects all versions up to and including 3.2.11. No patch or official fix has been documented at this time.

An attacker with Author-level or higher access can inject malicious JavaScript into testimonial pages, which executes when other users access those pages. This can lead to limited confidentiality and integrity impacts such as theft of session tokens or unauthorized actions performed on behalf of users. Availability is not affected. The vulnerability requires authenticated access, limiting the attack surface.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, limit user roles to trusted individuals and consider restricting access to testimonial custom fields. Monitor for updates from the plugin vendor and apply patches promptly when available.
