It has a limited risk. - The package overrides the install command in setup.py to execute malicious code during installation. ## Source: ossf-package-analysis (6d8ae54694435d049b0d7f0a1e37c940dd35b30ea4c50f51f1ec3c9d1390f38e) The OpenSSF Package Analysis project identified 'osopackagepy' @ 10.0.0 (pypi) as malicious.
