Is this vulnerability remotely exploitable?

It can be, depending on how the app receives imported files. If an attacker can cause the app to import a crafted file remotely (for example via shared links, inter-app communication, or cloud-synced content), exploitation does not require physical access to the device.

What level of access does an attacker need to exploit this issue?

The attacker must be able to control or significantly influence the file being imported, including its name or path-like metadata that the app uses when writing to storage. No direct system-level privileges are required beyond whatever the app itself already has.

What is the safest general fix pattern for developers?

Constrain all write operations to a fixed, canonical base directory, generate filenames on the server or within the app rather than trusting user input, and validate that any computed path stays within the allowed directory before performing file writes.
