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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:N/I:H/A:N","score":5.3},"cwes":["CWE-22"],"references":["https://github.com/blacklanternsecurity/bbot/commit/4fb38fd6e"],"products":[],"source":"nvd","synced_at":"2026-10-24T16:53:27.712498749+00:00"},"epss":{"cve":"CVE-2026-12565","score":0.00208,"percentile":0.10851,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-3vgw-585j-4m45","url":"https://osv.dev/vulnerability/GHSA-3vgw-585j-4m45","summary":"BBOT: Path traversal (Zip-Slip) in unarchive module - incomplete fix for CVE-2025-10284","modified":"2026-07-13T16:43:42.759504235Z","packages":[{"ecosystem":"PyPI","name":"bbot","purl":"pkg:pypi/bbot","ranges":[">=2.3.1 <2.8.5"],"fixed":["2.8.5"]}]},{"id":"PYSEC-2026-2392","url":"https://osv.dev/vulnerability/PYSEC-2026-2392","summary":"BBOT: Path traversal (Zip-Slip) in unarchive module - incomplete fix for CVE-2025-10284","modified":"2026-07-13T16:31:35.039404745Z","packages":[{"ecosystem":"PyPI","name":"bbot","purl":"pkg:pypi/bbot","ranges":[">=2.3.1 <2.8.5"],"fixed":["2.8.5"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
