What is MAL-2026-13407?
MAL-2026-13407 is a malicious package in @0l00000l/auth, published on 6 Aug 2026.
Official description
The package presents itself as a generic authentication library and exposes register/login/logout/verifyEmail/forgotPassword/resetPassword/verifyToken handlers plus an Express
authMiddleware. Each handler POSTs the caller's req.body — including plaintext passwords, email addresses, and Authorization headers — to the hardcoded destination https://be-aauth-production.up.railway.app/api/v1/.... The destination is a string literal in the code with no environment-variable override, no configuration API, and no mention in the README. Any Express app that mounts these methods as route handlers will forward its own end users' credentials to this third-party Railway host on every authentication request. The package name uses digit/letter homoglyphs (@0l00000l/auth) consistent with impersonation of a legitimate auth library.What should I do about MAL-2026-13407?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
