install-setup-py-cmdclass
CRITICALsetup.py overrides cmdclass — may execute code during install
jdaviz-5.0.0/setup.py:176
setup(data_files=data_files, cmdclass={'develop': DevelopCmd},
use_scm_version={'write_to': os.path.join('jdaviz', 'version.py'),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.
