Sandbox Breakout in safe-eval
Affected versions of safe-eval are vulnerable to a sandbox escape. By accessing object constructors, un-sanitized user input can access the entire standard library and effectively break out of the sandbox.
Proof of Concept:
This code accesses the process object and calls .exit()
var safeEval = require('safe-eval');
safeEval("this.constructor.constructor('return process')().exit()");
Recommendation
Update to version 0.4.0 or later

The safe-eval module describes itself as a safer version of eval. By accessing the object constructors, un-sanitized user input can access the entire standard library and effectively break out of the sandbox.
