setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and prune directives by matching compiled glob patterns against on-disk file names without Unicode normalization, so on macOS APFS or HFS+ an NFD file name could bypass an NFC exclusion rule and be packed into a source distribution. This issue is fixed in version 83.0.0.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-104947 advisory.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python
    packages. Prior to 83.0.0, FileList applied MANIFEST.in exclude, global-exclude, recursive-exclude, and
    prune directives by matching compiled glob patterns against on-disk file names without Unicode
