This enables the attacker to steal or manipulate data, perform a denial of service attack or enable additional attack types such as Cross Site Scripting. Nevertheless any website using Wordfence Firewall, were provided protection against this type of attack prior to discovery.

The Options Update vulnerability allows an attacker to access and make changes to the CDN (Content Delivery Network) options for the website. With this control an attacker can direct all requests for css files, images, videos, etc. to their site, allowing them to serve malicious content to visitors of the vulnerable site.
