CVE-2025-49596

The MCP inspector is a developer tool for testing and debugging MCP servers. Versions of MCP Inspector below 0.14.1 are vulnerable to remote code execution due to lack of authentication between the Inspector client and proxy, allowing unauthenticated requests to launch MCP commands over stdio. Users should immediately upgrade to version 0.14.1 or later to address these vulnerabilities.

Summary		(es) MCP Inspector es una herramienta para desarrolladores que permite probar y depurar servidores MCP. Las versiones de MCP Inspector anteriores a la 0.14.1 son vulnerables a la ejecución remota de código debido a la falta de autenticación entre el cliente Inspector y el proxy, lo que permite que solicitudes no autenticadas ejecuten comandos MCP a través de stdio. Los usuarios deben actualizar inmediatamente a la versión 0.14.1 o posterior para solucionar estas vulnerabilidades.
