      "value": "Mobile Next is an MCP server for mobile development and automation. Prior to version 0.0.49, the `@mobilenext/mobile-mcp` server contains a Path Traversal vulnerability in the `mobile_save_screenshot` and `mobile_start_screen_recording` tools. The `saveTo` and `output` parameters were passed directly to filesystem operations without validation, allowing an attacker to write files outside the intended workspace. Version 0.0.49 fixes the issue."

Antes de la versión 0.0.49, el servidor “@mobilenext/mobile-mcp” contiene una vulnerabilidad de salto de ruta en las herramientas “mobile_save_screenshot” y “mobile_start_screen_recording”. Los parámetros “saveTo” y “output” se pasaban directamente a operaciones del sistema de archivos sin validación, permitiendo a un atacante escribir archivos fuera del espacio de trabajo previsto. La versión 0.0.49 soluciona el problema."
