Mobilenexthq Mobile Mcp path traversal
- Published27 Mar 2026
Description
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.
