node.js security vulnerability

“Node.js is an open-source, JavaScript runtime environment which is built on Chrome’s V8 JavaScript engine”. Node.js support to event-driven, non-blocking I/O model that properties make node.js lightweight and efficient. It is designed to build scalable network applications.

Node.js enables the use of server-side JavaScript that makes is popular in the world and JavaScript is the most popular language because of its ease of use, scalability, performance. 

Why Node.js Security Matters?

When you are working on Node.js that means you are working with a huge amount of user data. Some of the data might be extremely sensitive. To keep your best node js hosting service data secure and safe node.js security is important.

What is npm and how is it related to security risks?

Npm is the default package manager for Node.js, and it is one of the largest open-source packages in the world. This increment in the developer productivity and performance of application.Node.js include numbers of or even thousands of npm packages.

Developers are not aware of the packages’ which are direct and indirect dependent and having the security hazards associated with them. Npm starts focusing on security issues in 2018. At the time of the npm audit release, it provides an npm audit security report that is a moment-in-time security review of a project’s. 

That security npm audit report contains information about node.js code security vulnerability and gives npm instructions and suggestions for further troubleshooting. That is the question of whether cheap web hosting India price companies look for security vulnerabilities and maintaining them properly.

Security in the Node.js

In 2020, for node.js security, the Security Working Group was formed, and this group mainly focusing on node.js security issues and node.js security testing.

It is mainly responsible for determining and managing security policies and procedures for the Node.js project and other projects.

This node.js security group also focus on:

  • The Node.js Security project collect vulnerability data.
  • Review and advise about some processes for approach of security reports.
  • Recommend some security changes for the core node.js project,
  • Provide some help and promote the expansion of a security service.

Some Reliable Information about Security Issues:

If you found a security issue and bug in Node.js, you should report it to 

Once you have done with the security report, your email will get answered within 24 hours. If there is any need, the security team will ask you in more detail in the next 48 hours.

Security in the Npm Ecosystem

NPM  is one of the largest package ecosystems in the world. These packages are generally downloaded more than 3 billion times every week. As the effective and responsible developer, npm, takes some important steps towards building npm more secure:

  • Transferring the whole traffic to https
  • Working on malware
  • Adding two-way authentication and read-only modes.

How to Secure your Node.js Applications:

You can improve the node.js security tips by using the following node.js security framework

  • Using the Helmet module:

Helmet module helps you to secure applications by using or by setting various HTTP headers, like:

  • X-Frame-Options These options are used to decreases clickjacking attacks.
  • Strict-Transport-Security module is used to keep your users on HTTPS.
  • X-XSS-Protection is used to block repeated XSS attacks.

Helmet module also supports a lot more headers, you can add helmet module to your applications by using the following code:

const express = require(‘express’)

continual helmet = require(‘helmet’)

consts app = express()


  • Validating user input

One of the most important things is validating user’s input when it comes to the security of your application.

If you fail to do this then it can open up a wide range of node.js security vulnerability attacks, such as command injection, SQL injection, etc.

To do validation of users input, the best libraries that you can pick is “joi”. It is an object schema language and validator that is used for JavaScript objects. 

The following example will explain you in better way:

  const Joi = require(‘joi’);

 const schema = Joi.object().keys({

     username: Joi.string().alphanum().min(3).max(30).required(),

     password: Joi.string().regex(/^[a-zA-Z0-9]{3,30}$/),

     access_token: [Joi.string(), Joi.number()],

     birthyear: Joi.number().integer().min(1900).max(2013),

     email: Joi.string().email()

 }).with(‘username’, ‘birthyear’).without(‘password’, ‘access_token’)

 // Return result

 const result = Joi.validate({

     username: ‘abc’,

     birthyear: 1994

 }, schema)

 // result.error === null -> valid

 When it validating user input it passed into SQL queries.

Secure Regular Expressions

Another way for node.js security tips is “Regular Expressions” are a great way to handle texts. However, there is an attack called Regular Expression Denial of Service attack that attacks can be handle by using regular expressions.

Final Thoughts

In this article you will get some information about how to better understand node.js security tips and what steps should you take to make your Node.js applications more secure.
