A flaw was found in setuptools, a Python package management tool. The FileList component, responsible for handling file exclusions, did not properly normalize Unicode file names when applying exclusion rules. This oversight could allow a specially crafted file name, using a different Unicode normalization form (NFD) on macOS APFS or HFS+ file systems, to bypass an intended exclusion rule (NFC). As a result, sensitive files that should have been excluded could be inadvertently included in a source distribution, leading to information disclosure.
