Due to insufficient validation of nested message keys during the processing of message data, an attacker can manipulate the prototype chain of JavaScript objects by providing specially crafted input. This can result in the injection of arbitrary properties into the Object.prototype, potentially leading to denial of service conditions or unexpected application behavior. The vulnerability allows attackers to alter the prototype of base objects, impacting all subsequent object instances throughout the application's lifecycle."}, {"lang": "es", "value": "Los componentes de tiempo de ejecuci\u00f3n del paquete messageformat para Node.js anteriores a la versi\u00f3n 3.0.1 contienen una vulnerabilidad de contaminaci\u00f3n de prototipos. Debido a la validaci\u00f3n insuficiente de claves de mensaje anidadas durante el procesamiento de datos de mensajes, un atacante puede manipular la cadena de prototipos de objetos JavaScript al proporcionar una entrada especialmente dise\u00f1ada. Esto puede resultar en la inyecci\u00f3n de propiedades arbitrarias en el Object.prototype, lo que podr\u00eda llevar a condiciones de denegaci\u00f3n de servicio o un comportamiento inesperado de la aplicaci\u00f3n. La vulnerabilidad permite a los atacantes alterar el prototipo de objetos base, impactando todas las instancias de objetos subsiguientes a lo largo del ciclo de vida de la aplicaci\u00f3n.
