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.

MCP-for-Stata 是一个 MCP（Model Context Protocol）服务器，旨在以“安全第一”的设计理念将 Stata 集成到智能体（agent）工作流中。在版本 1.19.0 之前， 中的 MCP 工具将用户控制的输入直接拼接到 Stata 命令字符串中，且未进行任何验证或清理（sanitization）。能够调用该 MCP 工具或等效 Python API 的攻击者，可以在 参数中嵌入换行符，从而注入任意 Stata 命令。由于 Stata 支持 shell 转义命令，这将导致在运行 St

Vulnerability Title
MCP-for-Stata: Stata Command Injection via Unsanitized `package` in `ado_package_install`
Source: CVE Program / CVE List V5
Vulnerability Description
MCP-for-Stata is a MCP server for integrating Stata into agent loops with a safety-first design. Prior to version 1.19.0, the ado_package_install MCP tool in stata-mcp concatenates user-controlled input directly into a Stata command string without any validation or sanitization. An attacker who can invoke the MCP tool or the equivalent Python API can embed newline characters in the package argument to inject arbitrary Stata commands. Because Stata supports a shell escape command, this leads to full OS-level arbitrary command execution (RCE) under the account running the Stata-MCP server. The tool is registered in the default all profile, so no non-default configuration is required. This issue has been patched in version 1.19.0.
