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

Gogs是Gogs团队开源的一个源代码管理软件。 Gogs 0.14.3之前版本存在服务端请求伪造漏洞，该漏洞源于仓库迁移功能中存在服务端请求伪造，应用程序只验证初始提交的URL主机名，但git clone --mirror会跟随HTTP重定向，可能导致经过身份验证的用户提交一个重定向到被阻止的内部端点（如127.0.0.1）的公共URL，将内部仓库内容导入攻击者控制的仓库。

Vulnerability Title
Gogs: Migration Redirect Bypass Leads to Internal Repository Theft
Source: CVE Program / CVE List V5
Vulnerability Description
Gogs is an open source self-hosted Git service. Prior to 0.14.3, a Server-Side Request Forgery (SSRF) vulnerability exists in the repository migration functionality. The application validates only the initially submitted URL hostname, but git clone --mirror follows HTTP redirects. An authenticated user can submit a public URL that redirects to a blocked internal endpoint (e.g., 127.0.0.1), importing the internal repository's contents into an attacker-controlled repository. This vulnerability is fixed in 0.14.3.
