# MAL-2026-10720: Malicious code in @vibelet/cli (npm)


- **Type:** Malicious package

## What is MAL-2026-10720?

MAL-2026-10720 is a malicious package in @vibelet/cli, published on 16 Jul 2026. 

### Official description

The @vibelet/cli package ships a daemon bundle (dist/index.cjs, invoked by the `vibelet` bin and by `vibelet start`/`restart`/`reset`) that starts an HTTP+WebSocket server, spawns an interactive PTY running process.env.SHELL via node-pty, and pipes network-received 'input' and 'resize' messages into that PTY. By default the CLI provisions a public Cloudflare tunnel (trycloudflare.com, using the bundled `cloudflared` and `ws` dependencies) that fronts this endpoint, so any remote party that pairs with the daemon (or obtains the tunnel URL together with the short-lived pair token) can execute arbitrary commands in a full interactive shell on the installer's host. The daemon bundle is packed with obfuscator.io-style transforms (string-array dispatcher `_0x9d44`, hex-encoded identifiers, control-flow flattening) rather than ordinary minification, which obscures the network-to-PTY path.

## What should I do about MAL-2026-10720?

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