Sandbox Breakout / Prototype Pollution in notevil
Versions of notevil prior to 1.3.3 are vulnerable to Sandbox Escape leading to Prototype pollution. The package fails to restrict access to the main context, allowing attacker to add or modify an object's prototype.
Evaluating the payload try{a[b];}catch(e){e.constructor.constructor('return __proto__.arguments.callee.__proto__.polluted=true')()} add the polluted property to Function.

Upgrade to version 1.3.3 or later.
