Clickjacking (User Interface redress attack, UI redress attack, UI redressing)
is a malicious technique of tricking a Web user into clicking on something different
from what the user perceives they are clicking on, thus potentially revealing
confidential information or taking control of their computer while clicking on
seemingly innocuous web pages.

The server didn't return an `X-Frame-Options` header which means that this website
could be at risk of a clickjacking attack.

The `X-Frame-Options` HTTP response header can be used to indicate whether or not
a browser should be allowed to render a page inside a frame or iframe. Sites can
use this to avoid clickjacking attacks, by ensuring that their content is not
embedded into other sites.
