Descriptions

Cross-origin resource sharing (CORS) enables browsers to perform cross domain requests in a controlled manner. 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.

Una compartición de recursos entre orígenes (CORS) permite a navegadores llevar a cabo peticiones entre dominios de forma controlada. Esta petición presenta un encabezado Origin que identifica el dominio que realiza la petición inicial y define el protocolo entre un navegador y un servidor para ver si la petición está permitida. Un atacante puede aprovecharse de esto y posiblemente llevar a cabo acciones privilegiadas y acceder a información confidencial cuando Access-Control-Allow-Credentials está habilitado
