{"id":"CVE-2026-12565","details":"The unarchive internal module's archive extraction commands perform no code-level validation on extracted file paths, relying entirely on the behavior of external tools (e.g. GNU tar) which varies by platform. While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extraction path traversal was never fixed. On systems with GNU tar \u003c 1.34 (Ubuntu 20.04, Debian Buster, CentOS 7, many Docker base images), a malicious archive can write files outside the intended extraction directory.","aliases":["GHSA-3vgw-585j-4m45","PYSEC-2026-2392"],"modified":"2026-07-15T07:32:05.336991Z","published":"2026-06-17T23:17:02.970Z","references":[{"type":"FIX","url":"https://github.com/blacklanternsecurity/bbot/commit/4fb38fd6e"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/blacklanternsecurity/bbot","events":[{"introduced":"0"},{"fixed":"4fb38fd6e"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-12565.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N"}]}
