## Summary

- **CVE ID:** CVE-2026-59890
- **Severity:** MEDIUM
- **CVSS Score:** 6.1 (CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N)
- **CWE:** CWE-176, CWE-697

## Description

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.

## Affected Products

- pypa — setuptools (< 83.0.0)
