This comes from ORT running

python-inspector --python-version 311 --operating-system linux --json-pdt /tmp/ort-PythonInspector1958014688763264125/python-inspector6282585536190674410.json --analyze-setup-py-insecurely --requirement /var/jenkins_home/workspace/ORT@tmp/project/source/anonymizer_module/test_requirements.txt --setup-py /var/jenkins_home/workspace/ORT@tmp/project/source/anonymizer_module/setup.py --verbose

@sschuberth Thanks for the report!

Looks like the issue disappeared with python-inspector release 0.11.0.

Sorry, no, I was not seeing the issue for another reason, but it's still there.
