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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.3},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":9.8},"cwes":["CWE-78"],"references":["https://github.com/gitpython-developers/GitPython/security/advisories/GHSA-v396-v7q4-x2qj","https://www.vulncheck.com/advisories/gitpython-authentication-bypass-via-joined-short-options"],"products":["gitpython_project:gitpython"],"source":"nvd","synced_at":"2026-10-24T16:53:34.184483516+00:00"},"epss":{"cve":"CVE-2026-67324","score":0.00644,"percentile":0.50601,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-v396-v7q4-x2qj","url":"https://osv.dev/vulnerability/GHSA-v396-v7q4-x2qj","summary":"GitPython unsafe clone option gate bypass through joined short options","modified":"2026-09-10T13:10:52.450096763Z","packages":[{"ecosystem":"PyPI","name":"gitpython","purl":"pkg:pypi/gitpython","ranges":[">=3.1.50 <3.1.51"],"fixed":["3.1.51"]}]},{"id":"PYSEC-2026-3947","url":"https://osv.dev/vulnerability/PYSEC-2026-3947","summary":"","modified":"2026-09-11T13:45:02.949863536Z","packages":[{"ecosystem":"PyPI","name":"gitpython","purl":"pkg:pypi/gitpython","ranges":[">=3.1.50 <3.1.51"],"fixed":["3.1.51"]}]}],"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).
