Stata mcp: MCP-for-Stata: Stata Command Injection via Unsanitized `package` in `ado_package_install` (CVE-2026-55071)
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.
AI Analysis
Technical Summary
MCP-for-Stata is a server tool integrating Stata into agent loops. In versions before 1.19.0, the ado_package_install MCP tool improperly handles the 'package' argument by concatenating it directly into a Stata command string without validation or sanitization. This allows an attacker who can invoke the MCP tool or its Python API to inject newline characters and arbitrary Stata commands. Since Stata supports shell escape commands, this injection leads to full OS-level remote code execution under the account running the Stata-MCP server. The tool is enabled by default in the all profile, requiring no special configuration to be vulnerable. The issue is tracked as CVE-2026-55071 and has a CVSS 3.1 score of 8.4 (high severity). A patch fixing this vulnerability was released in version 1.19.0.
Potential Impact
An attacker with the ability to invoke the vulnerable MCP tool or its API can execute arbitrary operating system commands with the privileges of the Stata-MCP server process. This can lead to full system compromise, data loss, or further lateral movement within the affected environment.
Mitigation Recommendations
A patch is available and should be applied by upgrading MCP-for-Stata to version 1.19.0 or later. This update properly sanitizes the 'package' argument to prevent command injection. No additional configuration changes are required since the vulnerable tool is enabled by default.
