install-setup-py-cmdclass
CRITICALsetup.py overrides cmdclass — may execute code during install

# in setup.py if it exists. We export it as a module-level variable.
cmdclass = {
"build_py": BuildUICommand,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.
