      "value": "Conform, a type-safe form validation library, allows the parsing of nested objects in the form of `object.property`. Due to an improper implementation of this feature in versions prior to 1.1.1, an attacker can exploit the feature to trigger prototype pollution by passing a crafted input to `parseWith...` functions. Applications that use conform for server-side validation of form data or URL parameters are affected by this vulnerability. Version 1.1.1 contains a patch for the issue.\n"

Debido a una implementaci\u00f3n incorrecta de esta caracter\u00edstica en versiones anteriores a la 1.1.1, un atacante puede explotar la caracter\u00edstica para desencadenar la contaminaci\u00f3n del prototipo pasando una entrada manipulada a las funciones `parseWith...`. Esta vulnerabilidad afecta a las aplicaciones que utilizan conform para la validaci\u00f3n del lado del servidor de datos de formulario o par\u00e1metros de URL. La versi\u00f3n 1.1.1 contiene un parche para el problema."
