CVE-2019-20149

ctorName in index.js in kind-of v6.0.2 allows external user input to overwrite certain internal attributes via a conflicting name, as demonstrated by 'constructor': {'name':'Symbol'}. Hence, a crafted payload can overwrite this builtin attribute to manipulate the type detection result.

Versions of `kind-of` 6.x prior to 6.0.3 are vulnerable to a Validation Bypass. A maliciously crafted object can alter the result of the type check, allowing attackers to bypass the type checking validation. ## Recommendation Upgrade to versions 6.0.3 or later.

La función ctorName en el archivo index.js en kind-of versión v6.0.2, permite que la entrada de un usuario externo sobrescriba ciertos atributos internos por medio de un nombre en conflicto, como es demostrado por 'constructor':{'name':'Symbol'}. Por lo tanto, una carga útil especialmente diseñada puede sobrescribir este atributo incorporado para manipular el resultado de detección de tipo.
