CVE-2026-2716

The Client Testimonial Slider plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'Testimonial Heading' setting in all versions up to, and including, 2.0. This is due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Administrator-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

Summary		(es) El plugin Client Testimonial Slider para WordPress es vulnerable a Cross-Site Scripting Almacenado a través de la configuración 'Testimonial Heading' en todas las versiones hasta la 2.0, inclusive. Esto se debe a una sanitización de entrada y un escape de salida insuficientes. Esto hace posible que atacantes autenticados, con acceso de nivel de Administrador o superior, inyecten scripts web arbitrarios en páginas que se ejecutarán cada vez que un usuario acceda a una página inyectada. Esto solo afecta a las instalaciones multisitio y a las instalaciones donde se ha deshabilitado unfiltered_html.
