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.
