# MAL-2026-14473: Malicious code in css-import-order (npm)

## What is MAL-2026-14473?

MAL-2026-14473 is a malicious package in css-import-order, published on 25 Aug 2026. 

### Official description

package.json declares the package's own name `css-import-order` as both a dependency and devDependency pointing at `http://pack.nppacks.com/npm/css-import-order` — a non-registry, plain-HTTP, unpinned URL under a domain unrelated to the npm publisher. On `npm install`, npm resolves and unpacks whatever tarball that host returns, executing any lifecycle scripts it contains. Because the source is not the npm registry, there is no integrity or version pinning, and the plain-HTTP transport additionally allows on-path substitution of the served bytes. The shipped index.js is a small benign transformer and carries a header comment reading `This package use for Security Research Testing Purpose.`, but the harmful vector is the install-time resolution to attacker-mutable content at pack.nppacks.com, not the local module code.

## What should I do about MAL-2026-14473?

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