FastMCP 操作系统命令注入漏洞

FastMCP is a MCP server building software developed by Jeremiah Lowin. Versions of FastMCP prior to 3.2.0 contained an operating system command injection vulnerability. This vulnerability could be exploited when a server name containing a shell metacharacter was used; commands could be executed o...

CVE-2026-32871

FastMCP is a Pythonic way to build MCP servers and clients. Prior to version 3.2.0, the OpenAPIProvider in FastMCP exposes internal APIs to MCP clients by parsing OpenAPI specifications. The RequestDirector class is responsible for constructing HTTP requests to the backend service. A vulnerabilit...
