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.
Malicious npm packages spread via worm-like propagation and steal developer credentials
The Bitwarden CLI was briefly compromised after attackers uploaded a malicious @bitwarden/cli package to npm containing a credential-stealing payload capable of spreading to other projects. [...]
Plus, the payload references 'TeamPCP/LiteLLM method' Yet another npm supply-chain attack is worming its way through compromised packages, stealing secrets and sensitive data as it moves through developers' environments, and it shares significant overlap with the open source infections attributed to TeamPCP last month.…
Cybersecurity researchers have flagged a fresh set of packages that have been compromised by bad actors to deliver a self-propagating worm that spreads through stolen developer npm tokens
A new supply chain attack targeting the Node Package Manager (npm) ecosystem is stealing developer credentials and attempting to spread through packages published from compromised accounts. [...]
