This vulnerability allows an attacker to overwrite arbitrary files on the system. By injecting specific options into the `git read-tree` command through methods like `IndexFile.from_tree`, `IndexFile.reset`, and `IndexFile.merge_tree`, without proper option validation or argument separation, an attacker can cause the application to write a git-index blob to any attacker-controlled writable path, leading to data destruction. ## 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-2026-76219.json) **gitpython: GitPython: Arbitrary File Overwrite via `git read-tree` option injection** — rated Important by Red Hat.
