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.
