At DSecured, our handcrafted approach to Node.js security examination ensures comprehensive vulnerability detection. Our seasoned experts manually simulate attacks to unearth weaknesses, giving your IT team the clear, detailed guidelines they need to boost defenses. Choose security crafted to perfection.
What we test in Node.js projects
Middleware chains, route handling, JWT validation, and API authorization for bypasses and IDOR vulnerabilities.
MongoDB injection, Mongoose query bypasses, Sequelize/TypeORM issues, and mass assignment vulnerabilities.
.env file exposures, source map leaks, hardcoded credentials, and development mode in production.
Node.js is the leading JavaScript runtime for modern backend development - fast, scalable, and perfect for microservices and real-time apps. But this flexibility comes at a price: misconfigurations in Express.js, exposed .env files, source map leaks, NoSQL injections, and vulnerable npm dependencies regularly lead to critical vulnerabilities - from information disclosure and authorization bypasses to full infrastructure takeovers.
Configuration & Source Map Leaks .env files, exposed .git directories, source maps in production, and debug mode enabled reveal credentials, API keys, and complete source code. Node.js deployments are frequently misconfigured.
Express.js & Authorization Issues Missing middleware validation, JWT bypasses, custom auth logic flaws, and race conditions in async/await code - Express.js is simple, but security must be actively implemented.
NoSQL Injection & Vulnerable Dependencies MongoDB injection via $where/$regex, Mongoose query bypasses, and critical CVEs in npm packages (prototype pollution, RCE) - the massive dependency tree is a security risk.
We deliver prioritized results with PoC code, concrete fix recommendations for your dev team, and - if desired - management summaries for stakeholders and compliance audits.

Leave us your contact details so that we can send you a non-binding, customized offer.
Your data will be treated confidentially and will not be passed on to third parties.
Benefit from our experienced team of bug bounty hunters and ethical hackers who have already carried out numerous successful Node.js penetration tests. Complex scopes and secured systems are no problem for us and are rather standard.
Receive detailed and understandable reports that not only highlight vulnerabilities, but also offer concrete and actionable recommendations. Our risk assessment is realistically tailored to your case.
Our innovative team uses creative and unconventional approaches to identify even the most hidden security vulnerabilities. We combine small flaws into critical vulnerabilities that no one expected.
Protect your business with targeted testing that minimizes potential security risks and secures your IT infrastructure. Black hats and cyber criminals are usually not long in coming and will exploit any weakness.
We tailor our communication to your needs, be it through regular updates, detailed discussions, or clear explanations. It doesn't matter whether it's via WhatsApp, Signal, or Slack. You decide!
Rely on a long-term collaboration that offers not just one-off tests, but continuous security optimizations and support. We can take any perspective and are your partner when it comes to security.
Node.js pentests uncover a wide range of vulnerabilities - from .env file leaks and NoSQL injections to Express.js bypasses, npm vulnerabilities, and OWASP Top 10.
Exposed .env files reveal database credentials, API keys, and JWT secrets. Source maps in production enable full source code reconstruction. .git directory exposures and debug mode are the classics.
Missing middleware validation, JWT verification bypasses, custom auth logic flaws, and IDOR via user-controlled parameters - Express.js is flexible, but security must be explicitly implemented.
MongoDB injections via $where/$regex, Mongoose query bypasses, mass assignment in schema validation, and operator injection ($ne, $gt) - NoSQL is not automatically SQL injection-safe.
Prototype pollution via lodash/merge, object property injections, command injections in child_process.exec(), and eval() usage regularly lead to remote code execution.
The massive dependency tree of Node.js projects is a paradise for known exploits. We scan with npm audit, Snyk, and exploit critical CVEs (prototype pollution, RCE, XSS).
Template injection in EJS/Pug, missing CSRF protection, race conditions in async/await code, and business logic flaws in payment/checkout flows - classic web vulnerabilities are common.
The price depends on complexity - simple Express.js APIs vs. microservice architectures with GraphQL, WebSockets, and complex authorization flows make the difference.
For simple Express.js APIs & Services
For Enterprise Microservices & Real-Time Apps
Our Mini Pentest for Node.js checks prototype pollution, insecure deserialization, npm package vulnerabilities and command injection risks. Ideal for Express/Nest.js APIs or serverless functions before production deployment.
Focused examination of the most critical vulnerabilities
Transparent fixed price - no hidden costs
Fast, actionable reporting as ticket list
Popular add-ons:
A large part of the internet is based on websites and web applications.
Modern websites and SPAs usually communicate with some kind of API.
Fully automated vulnerability scanning for your IT infrastructure or application.
We've had the privilege of working with some of the world's leading companies and strengthening their IT security.
In a Node.js penetration test, we frequently uncover security vulnerabilities such as code injection, insecure deserialization, and authentication issues. Our testers also focus on identifying specific vulnerabilities in the Node.js environment.
The duration of a Node.js penetration test can vary and depends heavily on the complexity and scope of your application. Typically, a comprehensive test takes between a few days and several weeks.
After completion of the penetration test, you will receive a detailed report containing a management summary, technical details of the vulnerabilities found, and tailored action recommendations.
We recommend conducting a comprehensive security review of your Node.js applications at least once a year. Depending on the frequency of changes and sensitivity of the data, a more frequent schedule may be advisable.
Yes, the findings from a Node.js security test can provide valuable insights that help you strengthen and adapt your security policies.
Preparation is key. Back up all important data, prepare your environment, and ensure that our testers have access to the necessary resources. Good communication beforehand can make the process significantly more efficient.
