Is this vulnerability remotely exploitable?

Yes. If remote users can influence the inputs passed to get_mime_type—such as file names, paths, or MIME-related parameters—the vulnerability can be exploited over the network without local access.

What level of access does an attacker need?

An attacker needs the ability to supply or control data that flows into get_mime_type. This often means being able to upload files, send crafted API requests, or otherwise control fields that the application uses when calling this function.

What is the safest general fix pattern?

The most robust fix is to remove shell-based MIME detection entirely and replace it with library-based MIME resolution that treats input as data only. If external utilities remain necessary, they should be invoked via non-shell APIs with strict argument handling and strong input validation.
