NodeJS — Vulnerabilities & Security Advisories 123

Node.js is a server-side JavaScript runtime environment primarily used for building scalable network applications and APIs. Its event-driven, non-blocking I/O architecture makes it popular for real-time services, yet this design introduces specific security challenges. Historically, the platform has been susceptible to Remote Code Execution (RCE) vulnerabilities, often stemming from prototype pollution or improper input validation in core modules. Cross-Site Scripting (XSS) and server-side request forgery (SSRF) are also frequent issues, particularly when handling untrusted user data or integrating with third-party libraries. With over 111 recorded Common Vulnerabilities and Exposures (CVEs), the ecosystem’s reliance on numerous npm packages amplifies supply chain risks. Notable incidents have included critical flaws in the HTTP parser and DNS resolution mechanisms, highlighting the necessity for rigorous dependency auditing and timely patching to mitigate exploitation of these systemic weaknesses in production environments.
