Package validation is the process of verifying that your library is correctly structured, configured, and ready to be consumed by others before you publish it. It's not about checking whether your logic works. That's what tests are for. It's about making sure your package metadata, entry points, module formats, and published files all line up so that consumers can install and use it without unexpected runtime errors.

The vulnerability, tracked as CVE-2026-1245 (CVSS score: N/A), affects all versions of the module prior to version 2.3.0, which addresses the issue. Patches for the flaw were released on November 26, 2025. Binary-parser is a widely used parser builder for JavaScript that allows developers to parse binary data. It supports a wide range of common data types, including integers, floating-point values, strings, and arrays. The package attracts approximately 13,000 downloads on a weekly basis.

Cybersecurity researchers have disclosed details of what has been described as a "sustained and targeted" spear-phishing campaign that has published over two dozen packages to the npm registry to facilitate credential theft. The activity, which involved uploading 27 npm packages from six different npm aliases, has primarily targeted sales and commercial personnel at critical infrastructure-adjacent organizations in the U.S. and Allied nations, according to Socket.

The second wave of the Shai-Hulud supply chain attack has spilled over to the Maven ecosystem after compromising more than 830 packages in the npm registry. The Socket Research Team said it identified a Maven Central package named org.mvnpm:posthog-node:4.18.1 that embeds the same two components associated with Sha1-Hulud: the "setup_bun.js" loader and the main payload "bun_environment.js." "This means the PostHog project has compromised releases in both the JavaScript/npm and Java/Maven ecosystems, driven by the same Shai Hulud v2 payload,"

A new version of the Shai-Hulud credentials-stealing self-propagating worm is expanding through the open npm registry, a threat that developers who download packages from the repository have to deal with immediately. Researchers at Wiz Inc. said Monday that in the early stages of the campaign late last week,a thousand new GitHub repositories containing harvested victim data were being added every 30 minutes. And researchers at JFrog identified 181 compromised packages.

The coordinated campaign has so far published as many as 46,484 packages, according to SourceCodeRED security researcher Paul McCarty, who first flagged the activity. The end goal is quite unusual - It's designed to inundate the npm registry with random packages rather than focusing on data theft or other malicious behaviors. The worm-life propagation mechanism and the use of a distinctive naming scheme that relies on Indonesian names and food terms for the newly created packages have lent it the moniker IndonesianFoods.

npm has taken down all versions of the real Stylus library and replaced them with a 'security holding' page, breaking pipelines and builds worldwide that rely on the package.

Deno 1.42 includes major updates for Node.js and NPM compatibility, enhancing modules such as async_hooks, crypto, and worker_threads for improved performance.

The Dockerfile demonstrates a streamlined setup for a Node.js application, starting from the lightweight Node.js 23-alpine image and ensuring the latest npm is installed.
