Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Grav 在 2.1.7 版本之前存在一个信息泄露漏洞，原因在于其内置的 nginx、lighttpd、IIS 和 Caddy 2 配置文件仅在文档根目录处阻止了 .git 的访问。未经身份验证的攻击者可以请求嵌套存储库（如 user/.git），以获取 Git 配置、引用和对象，从而重构未发布的提交历史或已提交的密钥信息。
