CRITICAL

setup.py executes code at install time

letsfg-1.0.19/letsfg/connectors/checkout_engine.py:20

  - CSS selectors for each element
  - Anti-bot setup (Kasada, Akamai, Cloudflare, PerimeterX)
  - Pre-navigation requirements (homepage pre-load for Kasada, etc.)
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.
