How to prevent cross site request forgery ( XSRF / CSRF ) attacks?
If local storage is used to store the token, CSRF vulnerability might be mitigated because values from local storage aren’t sent automatically to the server with every request. Thus, using local storage to store the antiforgery token on the client and sending the token as a request header is a recommended approach.
Do you need CSRF token for public API?
If you don’t want to require a CSRF Token for your public APIs, but need to need to store your auth in a cookie (to prevent XSS) for your SPA, what other options do we have to prevent CSRF? Recall that CSRF only occurs when a malicious site can trigger a request that will includes your auth cookie.
How to prevent cross site request forgery in ASP.NET Core?

How to use CSRF token in Django RESTful API and react?

If you are using React to render forms instead of Django templates you also need to render the csrf token because the Django tag { % csrf_token % } is not available at the client side so you need to create a higher order component that retrieves the token using the getCookie () function and render it in any form.
When do you need to use CSRF protection?
CSRF attacks depend upon this behavior. If you do not use cookies, and don’t rely on cookies for authentication, then there is absolutely no room for CSRF attacks, and no reason to put in CSRF protection. If you have cookies, especially if you use them for authentication, then you need CSRF protection.
Is it safe to use REST API endpoints?
So, you can still safely avoid dealing with CSRF on your REST APIs. But your login / authentication server better be bullet-proof (and CSRF protected). Rest API endpoints have a very important difference from other requests: they are specifically stateless, and should never accept/use data from either a cookie or session.
Is the Cors REST API intrinsically insecure?
Ultimately is a REST API that enables CORS intrinsically insecure. Even though CORS headers give you a mechanism for whitelisting clients it is based on HTTP and manually constructed HTTP requests can easily circumvent this. Granted a CORS config will prevent arbitrary embedding in website you don’t want, so is that all its good for.
