Para hacerlo, uri-js emplea una expresi\u00f3n regular que es vulnerable a una denegaci\u00f3n de servicio con expresiones regulares (ReDoS). Esto provoca que el programa se bloquee y que la CPU se vuelva inactiva al uso al 100% mientras uri-js intenta validar si la URL proporcionada es v\u00e1lida o no.
