CVE-2026-73624 is an arbitrary file overwrite vulnerability in GitPython affecting versions before 3.1.54. The flaw is in the Diffable.diff method, which insufficiently validates Git options forwarded through keyword arguments. An attacker can pass the Git --output option via the other parameter or the output keyword argument, causing generated patch content to be written to an attacker-chosen filesystem path. Because the write occurs with the privileges of the running process, the issue can be abused to overwrite files accessible to that process.

An arbitrary file overwrite vulnerability in GitPython's Diffable.diff method affecting versions before 3.1.54, caused by improper validation of git options passed through kwargs, allowing attackers to write patch content to attacker-chosen file paths with the privileges of the running process.
A high-severity GitPython unsafe option forwarding vulnerability in diff operations that can allow malicious options to be passed to the underlying Git command line, leading to argument injection and potentially arbitrary command execution.
