Descriptions

The Ninja Forms Contact Form WordPress plugin before 3.6.10 does not sanitise and escape field labels, allowing high privilege users to perform Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed.

El plugin Ninja Forms Contact Form de WordPress versiones anteriores a 3.6.10, no sanea ni escapa de las etiquetas de los campos, lo que permite a usuarios con altos privilegios llevar a cabo ataques de tipo Cross-Site Scripting incluso cuando la capacidad unfiltered_html no está permitida

The Ninja Forms Contact Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via field labels in versions up to, and including, 3.6.9 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers with administrative level permissions 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.
