This affects validate(). Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result."

Esto afecta a la funci\u00f3n validate(). Por lo tanto, una carga \u00fatil dise\u00f1ada puede sobrescribir este atributo incorporado para manipular el resultado de detecci\u00f3n de tipo."
