This has already been ensured with newer Python versions. Now, it is ensured with all supported versions, that means also with 3.10.0 - 3.10.12 and 3.11.0 - 3.11.4.
Further, 3.9.17 has been removed from
broken_tarfile_filterbecause we do not support Python 3.9 anymore.In addition, test coverage is increased.
Note: A path traversal during sdist extraction is not as critical as it might seem because after extracting the sdist the project is built, which may result in arbitrary code execution by design.
