Summary
Malicious code in routing-controls (npm)
Details
Package name `routing-controls` is a one-edit variant of the popular `routing-controllers` package (~1M weekly downloads), and the README and source are a near-verbatim clone. Inside `build/cjs/RoutingControllers.js` lines 84-88, the `executeAction` method contains a non-standard code path that fires on every POST action: it resolves `./util/lib.min.js`, deletes the entry from `require.cache`, and re-requires the file. In version 1.0.1 the target file `build/cjs/util/lib.min.js` (and its esm2015 sibling) is a 100-byte stub containing only `console.log('[routing-controls] POST route invoked at ' + new Date().toISOString());`, so no actively harmful behavior fires today. However, the misleading `.min.js` suffix on a stub file paired with a cache-busting reload on every POST is the structural shape of a hot-swappable trigger — a follow-up version could replace `lib.min.js` with arbitrary code that runs on every POST request in any application using this library. The current version exhibits no exfiltration, no remote fetch, no install-time execution, and no credential access; the harm is latent and depends on a future republication. ## Source: ghsa-malware (095efa733141879758b3a97acff66255dd2bc05143649513ab18b6597bf2dedb) 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.
