Reverse Tabnabbing

If tag with target="_blank" or uses window.open the hacker can replace original tab with opener.location="https://www.evilsite.com"; by opened page. It can be used in a phishing attack To fix it add rel="noopener" to and 'noopener' as third argument for window.open(: window.open('https://www.your.url','_blank','noopener')

HTTP Strict-Transport-Security (HSTS)

Add header Strict-Transport-Security: max-age=31536000; includeSubdomains; preload to make sure that the user once accessed the HTTPS version of the page will always be automatically redirected to it bypassing requests for HTTP.
