package/CHANGELOG.md:403
- Fixed offline startup hangs by adding offline startup behavior and network timeouts during managed tool setup ([#1631](https://github.com/badlogic/pi-mono/pull/1631) by [@mcollina](https://github.com/mcollina))
- Fixed Windows VT input initialization in ESM by loading koffi via createRequire, avoiding runtime and bundling issues in end-user environments ([#1627](https://github.com/badlogic/pi-mono/pull/1627) by [@kaste](https://github.com/kaste))Why was this flagged?
This setup.py calls subprocess, os.system, exec, or eval during package installation. Legitimate packages rarely need to execute arbitrary commands at install time. This pattern is commonly used by malicious packages to download and run payloads, exfiltrate environment variables, or establish persistence. Rated CRITICAL because it runs with the installer's full permissions.
