Attackers can inject the --index-output option to overwrite arbitrary files with a valid git-index blob, destroying existing file content at attacker-controlled writable paths.","published":"2026-08-19T14:17:48.187","modified":"2026-08-19T14:17:48.187","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-4gmw-gg2m-w46p"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/gitpython-before-arbitrary-file-overwrite-via-read-tree"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-19T14:17:48.187"}}
