Descriptions

In jpv (aka Json Pattern Validator) before 2.1.1, compareCommon() can be bypassed because certain internal attributes can be overwritten via a conflicting name, as demonstrated by 'constructor': {'name':'Array'}. This affects validate(). Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.

En jpv (también se conoce como Json Pattern Validator) versiones anteriores a 2.1.1, la función compareCommon() se puede omitir porque ciertos atributos internos pueden ser sobrescritos por medio de un nombre en conflicto, como es demostrado por 'constructor': {'name':'Array'}. Esto afecta a la función validate(). Por lo tanto, una carga útil diseñada puede sobrescribir este atributo incorporado para manipular el resultado de detección de tipo.
