## What is MAL-2026-13460?

MAL-2026-13460 is a malicious package in stretchshop, published on 6 Aug 2026. 

### Official description

package.json declares a postinstall hook that runs `node demo/demo.js base`, which shell-invokes `git clone https://github.com/Wradgio/StretchShop-demo-data.git` at mutable HEAD (no commit SHA, no tag, no integrity check) and then `childProcess.fork`s `db/demo_data.js` from the freshly cloned tree. The cloned repository is owned by the personal GitHub account `Wradgio`, which does not match the package's publisher scope `StretchShop`. Whoever controls that GitHub account can push arbitrary JavaScript to the default branch and have it executed on every fresh top-level install of stretchshop@0.7.5.

## What should I do about MAL-2026-13460?

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