CORS with credentials cannot use wildcard origin
CORS.*credentials.*wildcard|Access-Control-Allow-Origin.*\*.*credentials
Fixes
- 1.Replace Access-Control-Allow-Origin: * with the specific requesting origin when credentials are used
- 2.Read the Origin header from the request and echo it back (after validating it's allowed)
- 3.Set Access-Control-Allow-Credentials: true only with a specific, validated origin
