MAL-2026-10532
Source
OpenSSF Malicious Packages via OSV
Summary
Malicious code in fluterjs (npm)
Details
The package's main and bin entry, server.js, starts an Express server bound to 0.0.0.0:10459 that exposes POST /ejecutar. The handler reads the JSON field `comando` and passes it directly to child_process.exec with no authentication, no origin check, and no command allowlist. When an operator runs `fluter` or `npm start`, any network-reachable caller (LAN, container network, or the public internet if the host is exposed) obtains arbitrary shell command execution on the host as the user who launched the tool. The package presents itself as a terminal helper, but the shipped behavior is a remote shell distributed as a feature — a backdoor by design.
