Details

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()` ```js var safeEval = require('safe-eval'); safeEval("this.constructor.constructor('return process')().exit()"); ``` ## Recommendation Update to version 0.4.0 or later
