What is MAL-2026-5487?

MAL-2026-5487 is a malicious package in tailwind-form, published on 9 Jun 2026.

Official description

tailwind-form is a typosquat of the legitimate @tailwindcss/forms plugin (README and repository field are copied from tailwindlabs/tailwindcss-forms, but the package is published under an unrelated name by an unaffiliated author). The main module src/index.js ends with an eval that fetches https://www.jsonkeeper.com/b/NFTTN via axios and eval's the returned JSON field content_o. Any project that requires this package executes whatever JavaScript is currently hosted at that public, author-mutable paste URL — giving the publisher unconditional remote code execution on every installer's machine at module-load time.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

What should I do about MAL-2026-5487?

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