1) Improper Handling of Unicode Encoding (CVE-ID: CVE-2026-59890)

CWE-ID: CWE-176 - Improper Handling of Unicode Encoding

CVSSv4: 6.8 [CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information.

The vulnerability exists due to improper handling of unicode encoding in setuptools FileList manifest exclusion matching when building a source distribution on normalization-preserving filesystems with Unicode filenames. A remote attacker can trick the victim into building and publishing a source distribution containing a specially named file to disclose sensitive information.

User interaction is required to build and publish the source distribution, and the issue is specific to Unicode normalization collisions such as NFC/NFD on macOS APFS or HFS+.
