What is referrer policy security header?

The Referrer-Policy HTTP header controls how much referrer information (sent with the Referer header) should be included with requests. Aside from the HTTP header, you can set this policy in HTML.

What does insecure referrer policy affect?

Referrer Policy controls behaviour of the Referer header, which indicates the origin or web page URL the request was made from. The web application uses insecure Referrer Policy configuration that may leak user's information to third-party sites.

What should referrer policy be set to?

Consider setting a referrer policy of strict-origin-when-cross-origin . It retains much of the referrer's usefulness, while mitigating the risk of leaking data cross-origins. Don't use referrers for Cross-Site Request Forgery (CSRF) protection. Use CSRF tokens instead, and other headers as an extra layer of security.

Web developers may specify a referrer policy on their documents, which impacts the `Referer` header sent on outgoing requests and navigations. When no policy is specified, Chrome will now use strict-origin-when-cross-origin as the default policy, instead of no-referrer-when-downgrade.

How to set referrer policy in HTTP header?

What is insecure CORS?

An insecure CORS configuration allows any website to trigger requests with user credentials to the target application and read the responses, thus enabling attackers to perform privilegied actions or to retrieve potential sensitive information.

Can referrer be spoofed?

In HTTP networking, typically on the World Wide Web, referer spoofing (based on a canonised misspelling of "referrer") sends incorrect referer information in an HTTP request in order to prevent a website from obtaining accurate data on the identity of the web page previously visited by the user.

What does referrer mean in HTTP?
