Descriptions
The merge-deep library before 3.0.3 for Node.js can be tricked into overwriting properties of Object.prototype or adding new properties to it. These properties are then inherited by every object in the program, thus facilitating prototype-pollution attacks against applications using this library.
La biblioteca merge-deep versiones anteriores a 3.0.3, para Node.js puede ser engañado para sobrescribir propiedades de Object.prototype o añadirle nuevas propiedades. Estas propiedades son heredadas por todos los objetos del programa, facilitando así los ataques de contaminación de prototipos contra las aplicaciones que usan esta biblioteca
