Severity ?
10.0 (Critical) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H
Summary
Sandbox Breakout in safe-eval
Details

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() js var safeEval = require('safe-eval'); safeEval("this.constructor.constructor('return process')().exit()");

Recommendation

Update to version 0.4.0 or later
