Doc Text:
A flaw was found in GitPython. This vulnerability allows a remote attacker to overwrite arbitrary files on the system. By failing to properly validate git options passed to the `Diffable.diff` method, an attacker can supply a malicious output argument to write patch content to attacker-controlled file paths, leading to potential system compromise.

Description OSIDB Bzimport 2026-08-13 11:52:57 UTC 
GitPython versions before 3.1.54 contain an arbitrary file overwrite vulnerability in the Diffable.diff method that fails to validate git options passed through kwargs. Attackers can supply the --output argument via the other parameter or output kwarg to write patch content to attacker-chosen file paths at process privilege level.
