Is this vulnerability remotely exploitable?

Yes. If an attacker can interact with the invoice functionality and influence the Invoice Type configuration over HTTP, they can remotely trigger LFI. When combined with accessible upload paths, this can extend to remote code execution.

What level of access does an attacker need?

Typically, the attacker needs at least the level of access required to modify or indirectly control the Invoice Type configuration. In some deployments this may be an authenticated user role; in misconfigured setups, it could be exposed more broadly.

What is the safest general fix pattern?

Decouple user-controlled or configurable values from file paths entirely. Implement a fixed mapping from logical invoice types to non-user-editable template files stored in a dedicated directory, and ensure uploads cannot be selected or interpreted as templates.
