Which CORS configuration is safest for private APIs used by your web app?

Problem Statement

Explanation

C O R S controls which browser origins can read responses. For private data, specify exact origins you trust and require credentials only when needed. The wildcard with credentials is not allowed and would be unsafe even if it worked. Remember, CORS is a browser control. It is not an auth or firewall replacement.
