{"id":"CVE-2026-43637","aliases":["GHSA-rrh3-cwwj-g5mg"],"url":"https://o3.security/vulnerability/CVE-2026-43637","summary":"Cornac < 2.6.0 Path Traversal via _extract_archive() in download.py","details":"Cornac before 2.6.0 contains a path traversal (Tar Slip) vulnerability that allows attackers to write arbitrary files outside the intended cache directory by supplying a crafted TAR archive containing ../ sequences, absolute paths, or symlink/hardlink entries to the _extract_archive() function in cornac/utils/download.py. Attackers can trigger this vulnerability through the built-in dataset loaders, which automatically download and extract archives, causing archive.extractall() to write files to arbitrary locations on the filesystem accessible to the running process.","published":"2026-07-15T13:54:38.892Z","modified":"2026-11-09T22:11:20.744482960Z","cvss":null,"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"cornac","fixedVersion":"2.6.0"}],"fix":{"url":"https://github.com/PreferredAI/cornac/commit/8a50be72c11569b6747c6b96d6e31a0a1962f1a8","label":"PreferredAI/cornac@8a50be7"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43637.json"},{"type":"ADVISORY","url":"https://github.com/PreferredAI/cornac/releases/tag/v2.6.0"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43637"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/cornac-path-traversal-via-extract-archive-in-download-py"},{"type":"FIX","url":"https://github.com/PreferredAI/cornac/commit/8a50be72c11569b6747c6b96d6e31a0a1962f1a8"},{"type":"FIX","url":"https://github.com/PreferredAI/cornac/pull/709"},{"type":"PACKAGE","url":"https://github.com/PreferredAI/cornac"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-11-09T22:11:20.744482960Z"}}
