## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package's main entry (src/server.js) is a self-executing Express server that binds to 0.0.0.0 on port 3000 and exposes POST /execute, which passes the request body's \`command\` field directly to child\_process.exec with a 30-second timeout. The endpoint is gated by an API key read from process.env.RUNTIME\_API\_KEY, but the package's tarball includes a.env file containing RUNTIME\_API\_KEY=kalipto\_runtime\_secret\_123 — a shared secret known to anyone who downloads the package from npm. Because main points at this server, both \`npm start\` and \`require('kalipto-runtime')\` cause the listener to come up. Any installer who runs this package exposes an internet-reachable arbitrary-command-execution service to every network their host is attached to, authenticated by a publicly known key. This is a backdoor: any attacker with the package contents (i.e., anyone) can run arbitrary shell commands on any host running the package.

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.
