This vulnerability arises from insufficient guarding of git option forwarding within the `IndexFile.checkout()` and `TagReference.create()` functions. An authenticated attacker can exploit this by passing unsafe options through keyword arguments, leading to the ability to overwrite arbitrary files with repository content or read sensitive files. This could result in significant data integrity and confidentiality impacts.\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- **RHSA-2026:63385** · Red Hat · fixed in: Red Hat Satellite 6.19 for RHEL 9 · released 2026-09-03 · [advisory](https://access.redhat.com/errata/RHSA-2026:63385)\n- **RHSA-2026:67279** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.7 · released 2026-09-14 · [advisory](https://access.redhat.com/errata/RHSA-2026:67279)\n- **RHSA-2026:68764** · Red Hat · fixed in: Red Hat Satellite 6.18 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68764)\n- **RHSA-2026:68771** · Red Hat · fixed in: Red Hat Satellite 6.18 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68771)\n- **RHSA-2026:68780** · Red Hat · fixed in: Red Hat Satellite 6.19 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68780)\n- **RHSA-2026:68776** · Red Hat · fixed in: Red Hat Satellite 6.19 · released 2026-09-17 · [advisory](https://access.redhat.com/errata/RHSA-2026:68776)\n- **Red Hat VEX** · Important · affected: Exploit Intelligence, Migration Toolkit for Applications 8, Red Hat AI Inference Server, Red Hat Ansible Automation Platform 2, Red Hat Enterprise Linux AI (RHEL AI) 3, Red Hat OpenShift AI (RHOAI), … · no fix planned: Red Hat AI Inference Server, Red Hat Ansible Automation Platform 2, Exploit Intelligence, Migration Toolkit for Applications 8, … · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-73620.json)\n\n**gitpython: GitPython: Arbitrary file overwrite and read via unsafe git option forwarding** — rated Important by Red Hat.
