Synopsis

Missing 'X-Content-Type-Options' Header

Description

The HTTP 'X-Content-Type-Options' response header prevents the browser from MIME-sniffing a response away from the declared content-type.

The server did not return a correct 'X-Content-Type-Options' header, which means that this website could be at risk of a Cross-Site Scripting (XSS) attack.

Solution

Configure your web server to include an 'X-Content-Type-Options' header with a value of 'nosniff'.
