## What is MAL-2026-17314?

MAL-2026-17314 is a malicious package in test-supply-npm-lib-4, published on 30 Sep 2026. 

### Official description

package.json declares a dependency sourced from a git URL (git+https://git@github.com/agustedone/test-supply-npm-git-prepare-proof-4.git) pinned to commit 0abd2c55e475f12f58fb67ac487db4c1b00cf597, rather than from the npm registry. On `npm install`, npm clones that GitHub repository and runs any lifecycle scripts it contains, including a `prepare` hook indicated by the dependency's name. The dependency source is an individual GitHub account (agustedone/...) unrelated to any established publisher, and the fetched code is not subject to npm registry review or integrity checks against a registry tarball. Whoever controls that GitHub repository controls code executed on the installer's machine at install time.

## What should I do about MAL-2026-17314?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
