NVD Description

Note: Versions mentioned in the description apply only to the upstream python39:3.9/python39-requests package and not the python39:3.9/python39-requests package as distributed by AlmaLinux. See How to fix? for AlmaLinux:8 relevant fixed versions and status.

When using a TarFile.errorlevel = 0 and extracting with a filter the documented behavior is that any filtered members would be skipped and not extracted. However the actual behavior of TarFile.errorlevel = 0 in affected versions is that the member would still be extracted and not skipped.
