Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

GitPython是gitpython-developers开源的一个用于与 Git 存储库交互的 Python 库。 GitPython 3.1.49之前版本存在代码注入漏洞，该漏洞源于GitConfigParser.set_value()将值传递给Python的configparser时未验证换行符，可能导致攻击者注入core.hooksPath配置，任何调用钩子的Git操作将执行攻击者控制路径下的脚本。

Vulnerability Title
GitPython: Newline injection in config_writer().set_value() enables RCE via core.hooksPath
Source: CVE Program / CVE List V5
Vulnerability Description
GitPython is a python library used to interact with Git repositories. Prior to version 3.1.49, GitConfigParser.set_value() passes values to Python's configparser without validating for newlines. GitPython's own _write() converts embedded newlines into indented continuation lines (e.g. \n becomes \n\t), but Git still accepts an indented [core] stanza as a section header — so the injected core.hooksPath becomes effective configuration. Any Git operation that invokes hooks (commit, merge, checkout) will then execute scripts from the attacker-controlled path. This issue has been patched in version 3.1.49.
