@apai4: you're right. It was a browser extension!
Someone installed the CORS Toggle in this machine's Google Chrome that I'm using and it was enabled, causing this problem. I didn't see it.
Thank you!

You could check if there's any code that enable CORS twice.
from realworld.
CORS is enabled (once) to allow any origin
$ curl -X OPTIONS -D - -H 'Origin: http://localhost:4000' -H "Access-Control-Request-Method: POST" https://conduit.productionready.io/api/users
includes
Access-Control-Allow-Origin: http://localhost:4000
as a response header (no extra wildcard). Changing the URL in the Origin
request header will yield an Access-Control-Allow-Origin:
response header with only that URL as the value.
What browser are you using? Could it be a browser extension that's interfering with that header?
