A developer that opens a new window or tab with
target=‘_blank’ is exposing their users to a little known vulnerability which deals with a malicious code taking ownership of the new opened window.
This can be easily solved by appending
rel=“noopener noreferrer” to the anchor tags. With that said the URLs should look like this:
<a href="newpage.html" target="_blank" rel="noopener noreferrer">New Page</a>
