[Security] Bump static-eval from 2.0.0 to 2.1.0

[dependabot-preview[bot]]

Bumps static-eval from 2.0.0 to 2.1.0. This update includes a security fix.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Sandbox Breakout / Arbitrary Code Execution in static-eval Versions of static-evalprior 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.

Affected versions: <= 2.0.1

Release notes

Sourced from static-eval's releases.

v2.1.0

• Add allowAccessToMethodsOnFunctions option to restore 1.x behaviour so that cwise can upgrade. (@archmoj in #31)

  Do not use this option if you are not sure that you need it, as it had previously been removed for security reasons. There is a known exploit to execute arbitrary code. Only use it on trusted inputs, like the developer's JS files in a build system.

v2.0.5

• Fix function bodies being invoked during declaration. (@RoboPhred in #30)

v2.0.4

• Short-circuit evaluation in && and || expressions. (@RoboPhred in #28)
• Start tracking changes.

v2.0.3

Disallows accessing .constructor and .__proto__ properties, which could be used to access the Function() constructor. (browserify/static-eval#27) Thanks to an anonymous reporter!
