25 vulnerabilities to look out for in Node JS applications: Directory traversal, prototype pollution, XSSI, and more…

Securing applications is not the easiest thing to do. An application has many components: server-side logic, client-side logic, data storage, data transportation, API, and more. With all these components to secure, building a secure application can seem really daunting.

Thankfully, most real-life vulnerabilities share the same root causes. And by studying these common vulnerability types, why they happen, and how to spot them, you can learn to prevent them and secure your application.

The use of every language, framework, or environment exposes the application to a unique set of vulnerabilities. The first step to fixing vulnerabilities in your application is to know what to look for.

Today, let’s take a look at 25 of the most common vulnerabilities that affect Node.js applications, and how you can find and prevent them. The vulnerabilities I will cover in this post are:

  • Prototype pollution
  • Cross-site script inclusion (XSSI)
  • Insecure puppeteer settings
  • Security misconfiguration
