Is this vulnerability remotely exploitable?

Yes. As long as the nginx endpoint is network-accessible, an attacker can remotely send crafted HTTP requests with malicious query parameters to attempt path traversal.

Does an attacker need authenticated access to exploit this?

Not necessarily. If the vulnerable nginx location is exposed without authentication, an unauthenticated attacker can exploit it. If the affected paths are behind login, then valid credentials (or session) would be required.

What is the safest general fix pattern?

The safest pattern is to decouple path resolution from query parameters: avoid concatenating `$uri` and `$args`, strictly constrain all paths to a defined document root, and enforce path normalization with explicit rejection of traversal sequences.
