When an application passes attacker-influenced clone options into Repo.clone_from(..., multi_options=..., allow_unsafe_options=False), an attacker can supply -u<helper> to bypass the gate that blocks --upload-pack/-u, causing Git to execute the specified helper command during clone. Fixed in 3.1.51.","published":"2026-08-01T12:22:18.154Z","modified":"2026-09-05T03:48:03.713092850Z","cvss":null,"epss":{"score":0.0038,"percentile":0.31196,"asOf":"2026-09-07"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"gitpython","fixedVersion":"3.1.51"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67324.json"},{"type":"ADVISORY","url":"https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-v396-v7q4-x2qj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67324"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/gitpython-authentication-bypass-via-joined-short-options"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-09-05T03:48:03.713092850Z"}}
