This request has an Origin header that identifies the domain that is making the initial request and defines the protocol between a browser and server to see if the request is allowed. An attacker can take advantage of this and possibly carry out privileged actions and access sensitive information when the Access-Control-Allow-Credentials is enabled."

Esta petici\u00f3n presenta un encabezado Origin que identifica el dominio que realiza la petici\u00f3n inicial y define el protocolo entre un navegador y un servidor para ver si la petici\u00f3n est\u00e1 permitida.
