Is enabling Cors safe?

How do you fix a CORS problem?
Option 2: build a middleware. Since CORS is as simple as adding some HTTP headers, and it’s the only browser blocked, then you can build some proxy-like component that will basically make a call for you, get the response from the desired API, add those headers on top, and then send it back to Your UI.
What is a CORS policy?
Cross-Origin Resource Sharing (CORS) is a mechanism that uses additional HTTP headers to tell browsers to give a web application running at one origin, access to selected resources from a different origin. … The CORS mechanism supports secure cross-origin requests and data transfers between browsers and servers.

How do Cors work?

What is the purpose of Cors?
The purpose of CORS is to prevent a web browser that respects it from calling the server using non-standard requests with content served from a different location.
Why is Cors bad?
CORS isn’t bad practice. … CORS is not security. If servers have resources that need to be protected from certain users, it is not safe to rely solely on the Origin header to enforce this. Your server needs some other mechanism for security (such as OAuth2 and CSRF protection).
How does Cors help security?
Basically CORS allows your website js frontend code to access your website backend with the cookies and credentials entered in your browser while your backend stays protected from some other site’s js, asking client browser to access it (with credentials user has obtained).
