CVE-2024-8989

Status: DeferredMedium (6.4)—

The Free Responsive Testimonials, Social Proof Reviews, and Customer Reviews – Stars Testimonials plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's stars_testimonials shortcode in all versions up to, and including, 3.3.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.
