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. ## Vendor advisories - **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) - **RHSA-2026:71210** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.5 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71210) - **RHSA-2026:71179** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.6 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71179) - **RHSA-2026:71177** · Red Hat · fixed in: Red Hat Ansible Automation Platform 2.7 · released 2026-09-23 · [advisory](https://access.redhat.com/errata/RHSA-2026:71177) - **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) - **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) - **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) - **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) - **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 2026-09-24 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-76220.json) **gitpython: GitPython: Arbitrary command execution via crafted kwargs** — rated Important by Red Hat.

For detailed instructions how to apply this update, refer to: https://access.redhat.com/documentation/en-us/red_hat_satellite/6.19/html/updating_red_hat_satellite/index https://access.redhat.com/errata/RHSA-2026:63385 Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://docs.redhat.com/en/documentation/red_hat_ansible_automation_platform/2.5#Upgrading https://access.redhat.com/errata/RHSA-2026:71210 Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://docs.redhat.com/en/documentation/red_hat_ansible_automation_platform/2.6#Upgrade https://access.redhat.com/errata/RHSA-2026:71179 Workarounds / mitigations: - Do not pass untrusted or attacker-influenced keyword arguments to GitPython's guarded methods such as clone_from, and do not set split_single_char_options=False on untrusted input. Upgrade to GitPython 3.1.58 or later, where the check_unsafe_options bypass is fixed. ## Package advisory (CVE-2026-76220) Affected packages: - `gitpython < 3.1.58` Patched in: - `gitpython 3.1.58` Source: https://osv.dev/vulnerability/GHSA-wvpp-8hx9-p66j
