Vulnerability Title
GitPython: Unsafe option check validates multi_options before shlex.split transforms it
Source: NVD (National Vulnerability Database)
Vulnerability Description
GitPython is a python library used to interact with Git repositories. Prior to version 3.1.47, _clone() validates multi_options as the original list, then executes shlex.split(" ".join(multi_options)). A string like "--branch main --config core.hooksPath=/x" passes validation (starts with --branch), but after split becomes ["--branch", "main", "--config", "core.hooksPath=/x"]. Git applies the config and executes attacker hooks during clone. This issue has been patched in version 3.1.47.

GitPython 参数注入漏洞
Source: CNNVD (China National Vulnerability Database)
Vulnerability Description
GitPython是gitpython-developers开源的一个用于与 Git 存储库交互的 Python 库。 GitPython 3.1.47之前版本存在参数注入漏洞，该漏洞源于_clone()验证multi_options后执行shlex.split，可能导致字符串如--branch main --config core.hooksPath=/x绕过验证，导致Git在克隆期间应用配置并执行攻击者钩子。
