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.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Vendor advisories\n\n- **RHSA-2026:59135** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.5 for RHEL 8, Red Hat Ansible Automation Platform 2.5 for RHEL 9 · released 2026-08-24 · [advisory](https://access.redhat.com/errata/RHSA-2026:59135)\n- **RHSA-2026:59136** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 for RHEL 9 · released 2026-08-24 · [advisory](https://access.redhat.com/errata/RHSA-2026:59136)\n- **Red Hat VEX** · Important · affected: Red Hat Ansible Automation Platform 2, Red Hat OpenShift AI (RHOAI) · no fix planned: Red Hat Ansible Automation Platform 2, Red Hat OpenShift AI (RHOAI) · updated 2026-09-08 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-67324.json)\n- **RHSA-2026:65126** · Red Hat · fixed in: Red Hat OpenShift AI 2.25 · released 2026-09-08 · [advisory](https://access.redhat.com/errata/RHSA-2026:65126)\n\n## Package advisory (CVE-2026-67324)\n\nAffected packages:\n\n- `gitpython >= 3.1.50, < 3.1.51`\n\nPatched in:\n\n- `gitpython 3.1.51`\n\nSource: https://osv.dev/vulnerability/PYSEC-2026-3947","depth":"midnight","depthScore":54,"depthScoreParts":{"impact":53.9,"likelihood":0.1,"exploitation":0,"ransomware":0},"changes":[]}
