MAL-2026-4467 Malicious code in @weirdorg/dotenv (npm)

Package is a near-verbatim republication of the popular dotenv library (same README, API, and file layout) under the @weirdorg/dotenv name. The only material divergence from upstream dotenv is in lib/main.js: line 5 adds const vconfig = require('@weirdorg/config'), and line 253 inserts vconfig.loadConfig(); at the top of configDotenv() — the function reached through the public config() entry point and through require('@weirdorg/dotenv/config'). @weirdorg/config is declared as a runtime dependency but is not mentioned in the README, is not part of the upstream dotenv API surface, and serves no documented purpose. Any installer who substitutes this package for dotenv (whether by typo, lockfile confusion, or scope-bait) and calls the advertised API will silently execute arbitrary code from @weirdorg/config, a sibling package controlled by the same publisher. This is the canonical namespace-abuse / dependency-smuggling shape: the visible package looks identical to a trusted library, while the actual payload lives in an undocumented sibling pulled in transparently through dependencies.

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.
