Quick assessment

Affected
modelcontextprotocol servers
Exploitation
High exploitation probability; assess promptly
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Model Context Protocol Servers是Model Context Protocol开源的一个大模型上下文协议服务器。 Model Context Protocol Servers 2025.12.17之前版本存在路径遍历漏洞，该漏洞源于未验证后续工具调用中的repo_path参数是否在配置的路径内，可能导致对服务器进程可访问的其他仓库进行操作。

Vulnerability Title
mcp-server-git has missing path validation when using --repository flag
Source: CVE Program / CVE List V5
Vulnerability Description
In mcp-server-git versions prior to 2025.12.17, when the server is started with the --repository flag to restrict operations to a specific repository path, it did not validate that repo_path arguments in subsequent tool calls were actually within that configured path. This could allow tool calls to operate on other repositories accessible to the server process. The fix adds path validation that resolves both the configured repository and the requested path (following symlinks) and verifies the requested path is within the allowed repository before executing any git operations. Users are advised to upgrade to 2025.12.17 upon release to remediate this issue.
