从git提交信息中发现潜在软件漏洞。 输出格式为JSON，包含可能涉及软件漏洞修复的相关提交。搜索仅基于对提交信息的一组正则表达式。如果存在CVE ID，则会自动添加到输出中。输入可以是任何git仓库或GH archive源。
sudo apt install jq）git-vuln-finder 可以通过 poetry 安装。如果你没有安装 poetry，可以执行以下命令 curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python。
$ poetry install
$ poetry shell
$ git-vuln-finder -h
你也可以使用 pip。然后像这样导入：

usage: git-vuln-finder [-h] [-v] [-r R] [-o O] [-s S] [-p P] [-c] [-t] [-gh GH]
从git提交信息中发现潜在软件漏洞。
optional arguments:
-h, --help 显示此帮助信息并退出
-v 增加输出详细程度
-r R 要分析的git仓库
-o O 输出格式：[json]
-s S 找到的提交的状态
-p P 要使用的匹配模式：[vulnpatterns, cryptopatterns, cpatterns] - 模式'all'用于同时匹配所有模式。
-c 仅输出提交信息中发现的CVE模式列表（默认禁用）
-t 包含匹配特定提交的标签
-gh GH gharchive的特殊选项，传递一个包含PushEvent的JSON文件

git-vuln-finder 附带了3个默认模式，可以选择用来查找提交信息中描述的潜在漏洞，例如：
vulnpatterns 是一个通用漏洞模式，特别针对Web应用程序和通用安全提交信息。基于一篇学术论文。cryptopatterns 是一个用于提交信息中提到的加密错误的漏洞模式。cpatterns 是一组针对类C/C++语言的标准漏洞模式。$ git-vuln-finder -r ~/git/curl | jq .
