While CVE-2025-10284 addressed git-specific RCE vectors, the underlying archive extraction path traversal was never fixed. On systems with GNU tar < 1.34 (Ubuntu 20.04, Debian Buster, CentOS 7, many Docker base images), a malicious archive can write files outside the intended extraction directory.","published":"2026-06-17T23:17:02.970Z","modified":"2026-08-07T21:53:24.920595Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N"},"epss":{"score":0.00208,"percentile":0.10978,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"bbot","fixedVersion":"2.8.5"}],"fix":{"url":"https://github.com/blacklanternsecurity/bbot/commit/4fb38fd6e","label":"blacklanternsecurity/bbot@4fb38fd"},"references":[{"type":"FIX","url":"https://github.com/blacklanternsecurity/bbot/commit/4fb38fd6e"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-07T21:53:24.920595Z"}}
