A remote attacker can bypass the `check_unsafe_options` guard by combining a single-character keyword argument with `split_single_char_options=False`. This allows the attacker to supply a crafted dictionary of keyword arguments to guarded methods, such as `clone_from`, leading to arbitrary operating system command execution.\n\n## Vendor advisories\n\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-2026:68764** · 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: Red Hat Ansible Automation Platform 2, Red Hat Satellite 6 · no fix planned: Red Hat Ansible Automation Platform 2, Red Hat Satellite 6 · updated 2026-09-21 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-76220.json)\n\n**gitpython: GitPython: Arbitrary command execution via crafted kwargs** — rated Important by Red Hat.
