Is this vulnerability remotely exploitable?

Yes. If the `/utils/uploadFile` endpoint is exposed over the network, an attacker can exploit it remotely by submitting crafted file upload requests.

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

An attacker generally only needs the same level of access as a regular user capable of uploading files, which may be unauthenticated if the endpoint is public, or authenticated if uploads require login. No direct system-level access is required.

What is the safest general fix pattern for this issue?

The most robust pattern is to enforce strict allowlist-based server-side validation of file types and content, store uploads outside any executable or web-served directories, and ensure that any processing of uploaded files occurs in a minimally-privileged, sandboxed environment.
