  - setuptools is a package that allows users to download, build, install, upgrade, and uninstall Python
    packages. A path traversal vulnerability in `PackageIndex` is present in setuptools prior to version
    78.1.1. An attacker would be allowed to write files to arbitrary locations on the filesystem with the
    permissions of the process running the Python code, which could escalate to remote code execution
    depending on the context. Version 78.1.1 fixes the issue. (CVE-2025-47273)

Note that Nessus relies on the presence of the package as reported by the vendor.");
