Comment 1 Miro Hrončok 2025-09-25 07:56:12 UTC 
> this is a vulnerability in pip's fallback implementation of tar extraction for Python versions that don't implement PEP 706

Fedora's Python 3.6 has PEP 706, see https://src.fedoraproject.org/rpms/python3.6/blob/f42/f/00397-pep-706-cve-2007-4559-filter-api-for-tarfile-extractall.patch
