Node.js security covers vulnerabilities, dependency risks, and runtime defenses that can affect server-side applications and their data.

Background for this topic.
Node.js is an open-source, cross-platform runtime that executes JavaScript outside a web browser, using Google’s V8 engine. Its event-driven, non-blocking input/output model is widely used for web servers, APIs, command-line tools, and backend services. The runtime is not itself an application framework; security outcomes depend substantially on the code and modules running within it.
Security concerns include vulnerabilities in the Node.js runtime, insecure application logic such as injection or server-side request forgery, and risks from the large npm dependency ecosystem. Malicious or compromised packages, unsafe install scripts, transitive dependencies, and prototype-pollution flaws can expand an application’s attack surface. Practitioners should track runtime and package advisories, use lockfiles and dependency review, restrict package-install and process permissions where practical, validate untrusted input, and protect credentials and session data. During incidents, dependency inventories and build records help determine whether a vulnerable module or runtime was deployed.
Hackers have injected credential-stealing malware into newly published versions of node-ipc, a popular inter-process communication package, in a new supply chain attack targeting npm. [...]
Attackers stole a limited amount of internal credential material after malware hidden in poisoned packages reached two staff machines
OpenAI says two employees' devices were breached in the recent TanStack supply chain attack that impacted hundreds of npm and PyPI packages, causing the company to rotate code-signing certificates for its applications as a precaution. [...]
Cybersecurity researchers are sounding the alarm about what has been described as "malicious activity" in newly published versions of node-ipc
Malicious npm Package Lets Attackers Capture Refreshed TokensA researcher has mapped a five-step attack on Claude Code that intercepts the credentials giving AI agents access to Jira, GitHub and Confluence, and demonstrated that the standard incident response move, rotating the stolen token, hands the attacker a fresh one.
Latest Mini Shai-Hulud Worm Steals Credentials, Includes Wiper, Now Open SourceA new Shai-Hulud variant has infected multiple npm repositories and jumped to other widely used JavaScript and Python packages. Designed to rapidly propagate, the worm steals over 100 different types of credentials and can wipe systems, including if developers try to delete it.
Mini Shai-Hulud compromises TanStack npm packages and spreads across PyPI
Six-minute supply chain blitz pushed 84 malicious versions with credential theft and disk-wiping code
TeamPCP, the threat actor behind the recentsupply chain attack spree, has been linked to the compromise of the npm and PyPI packages from TanStack, UiPath, Mistral AI, OpenSearch, and Guardrails AI as part of a fresh Mini Shai-Hulud campaign
Hundreds of packages across npm and PyPI have been compromised in a new Shai-Hulud supply-chain campaign delivering credential-stealing malware targeting developers. [...]
Hundreds of npm packages infected by the self-propagating, credential-stealing worm from TeamPCP are related to the open source TanStack ecosystem.
