Doc Text:
A flaw was found in GitPython. This vulnerability allows a remote attacker to achieve arbitrary code execution. By supplying a specially crafted template parameter to the `Repo.init` function, an attacker can point to a directory containing malicious Git hooks. When Git operations are performed on the initialized repository, these hooks execute arbitrary code, leading to a complete compromise of the affected system.

Description OSIDB Bzimport 2026-08-19 14:18:10 UTC 
GitPython before 3.1.58 contains a remote code execution vulnerability in Repo.init that forwards unsafe git options without validation. Attackers can supply a template parameter pointing to a directory with malicious git hooks that execute arbitrary code when git operations are performed on the initialized repository.
