Exploitation
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 3.1.59 之前的版本在解析 .gitmodules 文件时，未能禁用 merge_includes 选项，攻击者可以通过 [include] 指令包含任意文件路径，从而泄露本地文件内容。攻击者可以构造一个恶意的 .gitmodules 文件，其中的 include 指令指向敏感文件；当访问 repo.submodules 时，GitConfigParser 会抛出 MissingSectionHeaderError 异常，异常消息中将按原文嵌入目标文件的第一行内容。

Vulnerability Title
GitPython before 3.1.59 Local File Content Disclosure via .gitmodules
Source: CVE Program / CVE List V5
Vulnerability Description
GitPython before 3.1.59 fails to disable merge_includes when parsing .gitmodules, allowing attackers to disclose local file content by including arbitrary file paths via [include] directives. Attackers can craft a malicious .gitmodules file with include directives pointing to sensitive files; when repo.submodules is accessed, GitConfigParser raises MissingSectionHeaderError embedding the target file's first line verbatim in the exception message.
