High [CVE-2026-67323] Arbitrary code execution via command injection due to unguarded Git options

GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution).

Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output= can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.

This vulnerability allows an attacker to inject arbitrary commands when using functions like Repo.archive() and git.ls_remote(), potentially leading to arbitrary code execution. This is an Important vulnerability because it allows for arbitrary code execution or file truncation.

This could lead to a compromise of confidentiality, integrity, and availability on affected Red Hat products that utilize GitPython in such a manner. Red Hat severity: Important — CVSS 8.4 (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).

Weakness: CWE-88.
