Descriptions

The Ninja Forms Contact Form WordPress plugin before 3.6.34 does not sanitize and escape its label fields, which could allow high privilege users such as admin to perform Stored XSS attacks. Only users with the unfiltered_html capability can perform this, and such users are already allowed to use JS in posts/comments etc however the vendor acknowledged and fixed the issue

El complemento Ninja Forms Contact Form para WordPress anterior a 3.6.34 no sanitiza ni escapa de sus campos de etiqueta, lo que podría permitir a usuarios con altos privilegios, como el administrador, realizar ataques XSS almacenados. Solo los usuarios con la capacidad unfiltered_html pueden realizar esto, y dichos usuarios ya pueden usar JS en publicaciones/comentarios, etc. Sin embargo, el proveedor reconoció y solucionó el problema.

The Ninja Forms Contact Form plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 3.6.33 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-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.
