Is this vulnerability remotely exploitable?

Yes. Any remote user who can reach the affected WordPress site's scan_qr.php endpoint can potentially exploit the issue without logging in, as the vulnerability exists in an unauthenticated QR scanning interface.

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

No prior access is needed beyond the ability to send HTTP requests to the site. The attacker does not need a WordPress account, customer account, or knowledge of specific order identifiers because they can iterate through sequential post IDs.

What is the safest general fix pattern for this type of issue?

Implement strict server-side authorization checks for every request that retrieves order or ticket data, ensuring that the requester is authenticated and is the owner (or otherwise explicitly permitted) to access that specific resource. Additionally, avoid using predictable identifiers alone as a gatekeeper and consider using unguessable, per-order tokens for QR-based lookups.
