{"id":"GHSA-rrh3-cwwj-g5mg","summary":"Cornac: 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.","aliases":["CVE-2026-43637"],"modified":"2026-11-09T22:00:07.747118929Z","published":"2026-07-15T15:33:06Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-11-09T21:46:35Z","nvd_published_at":"2026-07-15T14:18:10Z","cwe_ids":["CWE-22"],"severity":"HIGH"},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43637"},{"type":"WEB","url":"https://github.com/PreferredAI/cornac/pull/709"},{"type":"WEB","url":"https://github.com/PreferredAI/cornac/commit/8a50be72c11569b6747c6b96d6e31a0a1962f1a8"},{"type":"PACKAGE","url":"https://github.com/PreferredAI/cornac"},{"type":"WEB","url":"https://github.com/PreferredAI/cornac/releases/tag/v2.6.0"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/cornac-path-traversal-via-extract-archive-in-download-py"}],"affected":[{"package":{"name":"cornac","ecosystem":"PyPI","purl":"pkg:pypi/cornac"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.0"}]}],"versions":["0.1.0","0.1.0.post1","0.1.0.post2","0.1.0.post3","0.1.0.post4","0.1.0.post5","0.2.0","0.2.1","0.3.0","0.3.1","0.3.2","0.3.3","0.3.4","0.3.5","1.0.0","1.1.0","1.1.1","1.1.2","1.10.0","1.11.0","1.12.0","1.13.0","1.13.1","1.13.2","1.13.3","1.13.4","1.13.5","1.14.0","1.14.1","1.14.2","1.15.0","1.15.1","1.15.2","1.15.3","1.15.4","1.16.0","1.17.0","1.18.0","1.2.0","1.2.1","1.2.2","1.3.0","1.3.1","1.4.0","1.4.1","1.5.0","1.5.1","1.5.2","1.6.0","1.6.1","1.7.0","1.7.1","1.8.0","1.9.0","2.0.0","2.1.0","2.2.0","2.2.1","2.2.2","2.3.0","2.3.1","2.3.2","2.3.3","2.3.4","2.3.5","2.4.0","2.5.0"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/07/GHSA-rrh3-cwwj-g5mg/GHSA-rrh3-cwwj-g5mg.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
