How broadly exploitable is this vulnerability?

Exploitability depends on who can invoke the Mobile Next MCP tools and control the `saveTo` or `output` parameters. In environments where these tools are exposed to untrusted or semi-trusted clients, the vulnerability can be exploited remotely through normal tool invocation.

Does an attacker need special privileges to exploit this?

The attacker needs whatever level of access is required to call `mobile_save_screenshot` or `mobile_start_screen_recording` and supply custom path parameters. No direct OS-level privileges are required beyond the permissions already granted to the MCP server process.

What is the safest general fix pattern?

Enforce strict path handling by resolving all user-supplied paths against a predefined workspace root, rejecting any path that escapes that directory, and constructing output paths primarily from trusted server-side directory definitions.
