There is an issue in CPython when using `bytes.decode("unicode_escape", error="ignore|replace")`. If you are not using the "unicode_escape" encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError.

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2025-1044 advisory.

    Allows modifying some file metadata (e.g. last modified) with filter=data or file permissions (chmod)     with filter=tar of files outside the extraction directory.You are affected by this vulnerability if     using the tarfile module to extract untrusted tar archives using TarFile.extractall() or TarFile.extract()     using the filter= parameter with a value of data or tar. See the tarfile  extraction filters     documentation https://docs.python.org/3/library/tarfile.html#tarfile-extraction-filter  for more     information. Only Python versions 3.12 or later are affected by these vulnerabilities, earlier versions     don't include the extraction filter feature.

    Note that for Python 3.14 or later the default value of filter= changed from no filtering to `data, so     if you are relying on this new default behavior then your usage is also affected.

    Note that none of these vulnerabilities significantly affect the installation of source distributions     which are tar archives as source distributions already allow arbitrary code execution during the build     process. However when evaluating source distributions it's important to avoid installing source     distributions with suspicious links. (CVE-2024-12718)

    Allows the extraction filter to be ignored, allowing symlink targets to point outside the destination     directory, and the modification of some file metadata.

    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. (CVE-2025-4435)
