Descriptions

This affects the package set-value before <2.0.1, >=3.0.0 <4.0.1. A type confusion vulnerability can lead to a bypass of CVE-2019-10747 when the user-provided keys used in the path parameter are arrays.

Esto afecta al paquete set-value anterior a la versión 2.0.1, posterior o igual a la versión 3.0.0 y anterior a la versión 4.0.1. Una vulnerabilidad de confusión de tipos puede conducir a una derivación de CVE-2019-10747 cuando las claves proporcionadas por el usuario utilizadas en el parámetro de ruta son matrices

A type confusion vulnerability in nodejs-set-value can lead to a bypass of CVE-2019-10747. If the user-provided keys used in the path parameter are arrays, the function mixin-deep can be tricked into adding or modifying properties of Object.prototype using any of the constructor, prototype, or _proto_ payloads. This vulnerability can impact data confidentiality, integrity, and availability.
