{"id":"CVE-2026-59890","summary":"setuptools: MANIFEST.in exclusion bypass in sdist via Unicode normalization collision (NFC/NFD) on macOS APFS/HFS+","details":"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.","aliases":["BIT-setuptools-2026-59890","GHSA-h35f-9h28-mq5c","PYSEC-2026-3447"],"modified":"2026-07-14T10:56:37.948360943Z","published":"2026-07-08T16:02:07.519Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59890.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-176","CWE-697"]},"references":[{"type":"WEB","url":"https://github.com/pypa/setuptools/releases/tag/v83.0.0"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59890.json"},{"type":"ADVISORY","url":"https://github.com/pypa/setuptools/security/advisories/GHSA-h35f-9h28-mq5c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59890"},{"type":"FIX","url":"https://github.com/pypa/setuptools/commit/dd9f436a36486b4cb8a4c70a2321548b0be09b8f"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pypa/setuptools","events":[{"introduced":"0"},{"fixed":"dd9f436a36486b4cb8a4c70a2321548b0be09b8f"},{"fixed":"6519f728c6f23c992df81a5691ef7655184a20eb"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"83.0.0"}]}}],"versions":["v82.0.1","v82.0.0","v75.3.4","v81.0.0","v80.10.2","v80.10.0","v80.10.1","v80.9.0","v80.8.0","v80.7.1","v80.7.0","v80.6.0","v80.5.0","v80.4.0","v80.3.1","v80.3.0","v80.2.0","v80.1.0","v80.0.1","v80.0.0","v79.0.1","v79.0.0","v78.1.1","v78.1.0","v78.0.2","v78.0.1","v78.0.0","v77.0.3","v77.0.1","v77.0.2","v77.0.0","v76.1.0","v75.3.2","v75.3.0","v76.0.0","v75.9.1","v75.9.0","v75.8.2","v75.8.1","v75.8.0","v75.7.0","v75.6.0","v75.5.0","v75.4.0","v75.2.0","v75.1.1","v75.1.0","v75.0.0","v74.1.2","v74.1.1","v74.1.0","v74.0.0","v73.0.1","v73.0.0","v72.2.0","v72.1.0","v72.0.0","v71.1.0","v71.0.4","v71.0.3","v71.0.2","v71.0.1","v71.0.0","v70.3.0","v70.2.0","v70.1.1","v70.1.0","v70.0.0","v69.5.1","v69.5.0","v69.4.0","v69.3.0","v69.2.0","v69.1.1","v69.1.0","v69.0.2","v69.0.1","v69.0.0","v68.2.2","v68.2.1","v68.2.0b1","v68.2.0","v68.1.2","v68.1.1","v68.1.0","v68.0.0","v67.8.0","v67.7.2","v67.7.1","v67.7.0","v67.6.1","v67.6.0","v67.5.1","v67.5.0","v67.4.0","v67.3.3","v67.3.2","v67.3.1","v67.3.0","v67.2.0","v67.1.0","v67.0.0","v66.1.1","v66.1.0","v66.0.0","v65.7.0","v65.6.3","v65.6.2","v65.6.1","v65.6.0","v65.5.1","v65.5.0","v65.4.1","v65.4.0","v65.3.0","v65.2.0","v65.1.1","v65.1.0","v65.0.2","v65.0.1","v65.0.0","v64.0.3","v64.0.2","v64.0.1","v64.0.0","v63.4.3","v63.4.2","v63.4.1","v63.4.0","v63.3.0","v63.2.0","v63.1.0","v63.0.0","v62.6.0","v62.5.0","v62.4.0","v62.3.4","v62.3.3","v62.3.2","v62.3.1","v62.3.0","v62.2.0","v62.1.0","v62.0.0","v61.3.1","v61.3.0","v61.2.0","v61.1.1","v61.1.0","v61.0.0","v60.10.0","v60.9.3","v60.9.2","v60.9.1","v60.9.0","v60.8.2","v60.8.1","v60.8.0","v60.7.1","v60.7.0","v60.6.0","v60.5.4","v60.5.3","v60.5.2","v60.5.1","v60.5.0","v60.4.0","v60.3.1","v60.3.0","v60.2.0","v60.1.1","v60.1.0","v60.0.5","v60.0.4","v60.0.3","v60.0.0","v60.0.2","v60.0.1","v59.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59890.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N"}]}
