{"id":"CVE-2026-43637","state":"PUBLISHED","title":"Cornac < 2.6.0 Path Traversal via _extract_archive() in download.py","description":"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.","publishedAt":"2026-07-15T13:54:38.892Z","updatedAt":"2026-07-15T14:41:32.022Z","severity":{"score":8.8,"label":"High","version":"4.0","vector":"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","source":"VulnCheck"},"assigner":"VulnCheck","products":["PreferredAI cornac"],"affected":[{"vendor":"PreferredAI","product":"cornac","defaultStatus":"affected","versions":[{"version":"0","status":"affected","lessThan":"2.6.0","versionType":"semver"}],"repo":"https://github.com/PreferredAI/cornac"}],"references":["https://github.com/PreferredAI/cornac/releases/tag/v2.6.0","https://github.com/PreferredAI/cornac/pull/709","https://github.com/PreferredAI/cornac/commit/8a50be72c11569b6747c6b96d6e31a0a1962f1a8","https://www.vulncheck.com/advisories/cornac-path-traversal-via-extract-archive-in-download-py"],"weaknesses":["CWE-22"],"ingestedAt":"2026-10-29T20:11:57.932Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/43xxx/CVE-2026-43637.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-43637","state":"PUBLISHED","datePublished":"2026-07-15T13:54:38.892Z","dateUpdated":"2026-07-15T14:41:32.022Z","assignerShortName":"VulnCheck","assignerOrgId":"83251b91-4cc7-4094-a5c7-464a1b83ea10","dateReserved":"2026-05-01T18:22:45.642Z"},"containers":{"cna":{"title":"Cornac < 2.6.0 Path Traversal via _extract_archive() in download.py","descriptions":[{"lang":"en","value":"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.
