How widely exploitable is this vulnerability?

Exploitability depends on how easily an attacker can cause the app to import a crafted file—such as by sending a file via messaging, email, or cloud share and convincing the user or another app to open it with InTouch. Where such interactions are common, the practical attack surface is significant.

Does exploiting this require physical access to the device?

Physical access is not strictly required. An attacker typically needs only a remote channel to deliver a malicious file to the device and a way to have it opened by the vulnerable app, which may occur through normal user interactions.

What is the safest general fix pattern for developers?

Constrain all imported files to be written inside a dedicated, non-executable directory using framework-provided safe storage APIs, generate internal filenames independent of user-controlled values, and reject any path that resolves outside the intended directory after canonicalization.
