Descriptions

Auth. (admin+) Stored Cross-Site Scripting (XSS) vulnerability in Saturday Drive's Ninja Forms Contact Form plugin <= 3.6.9 at WordPress via "label".

Una vulnerabilidad de tipo Cross-Site Scripting (XSS) almacenado y autenticado (rol de administrador o usuario superior) en el plugin Ninja Forms Contact Form versiones anteriores a 3.6.9 incluyéndola, de Saturday Drive en WordPress por medio de "label"

The Ninja Forms Contact Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'label' parameter 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.
