Descriptions

The NEX-Forms WordPress plugin before 8.4.3 does not have CSRF checks in place when editing a form, and does not escape some of its settings as well as form fields before outputting them in attributes. This could allow attackers to make a logged in admin edit arbitrary forms with Cross-Site Scripting payloads in them

El plugin NEX-Forms de WordPress versiones hasta 7.9.4, no escapa algunos de sus ajustes y campos form antes de mostrarlos en atributos, lo que podría permitir a usuarios muy privilegiados llevar a cabo ataques de tipo Cross-Site Scripting incluso cuando la capacidad unfiltered_html está deshabilitada

The NEX-Forms plugin for WordPress is vulnerable to Cross-Site Request Forgery in versions up to, and including, 8.4.2. This is due to missing or incorrect nonce validation on the update_record() function, in addition to many other functions. This makes it possible for unauthenticated attackers to modify the plugin's settings and inject malicious JavaScripts via a forged request granted they can trick a site administrator into performing an action such as clicking on a link.
