Public or AI PoC available; prioritize validation
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

gitpython-developers GitPython是gitpython-developers组织的数据库系统。 gitpython-developers GitPython 3.1.51之前版本存在命令注入漏洞，该漏洞源于Repo.archive()和git.ls_remote()未防范危险的Git选项作为关键字参数，可能导致命令注入；同时Repo.iter_commits()和Repo.blame()未检查前导破折号修订参数，可导致打开并截断任意文件。

Vulnerability Title
GitPython before 3.1.51 Command Injection via unguarded Git options
Source: CVE Program / CVE List V5
Vulnerability Description
GitPython before 3.1.51 fails to guard against dangerous Git options passed as keyword arguments in Repo.archive() and git.ls_remote(), allowing command injection via options such as --exec/--upload-pack (leading to arbitrary command execution). Additionally, Repo.iter_commits() and Repo.blame() do not check for leading-dash revision arguments, so a revision like --output=<path> can cause Git to open and truncate an arbitrary file. Exploitation requires an application that passes attacker-controlled arguments to these methods.
