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.

Affected: npm: 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 ```js 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.
