install-setup-py-cmdclass
CRITICALsetup.py overrides cmdclass — may execute code during install
fleet_rlm-0.4.99/setup.py:54
setup(cmdclass={"build_py": build_py, "sdist": sdist})Why was this flagged?
This package overrides Python's setup.py cmdclass, which allows arbitrary code to execute during pip install. This is the primary attack vector for malicious PyPI packages — attackers use it to steal credentials, install backdoors, or download additional payloads before the developer ever runs the code. Rated CRITICAL because it executes automatically with no user interaction required.
install-pip-setup-exec
CRITICALsetup.py executes code at install time

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.
