Is this vulnerability remotely exploitable?

Yes. The weakness can be exploited remotely as long as the attacker can reach the `/deluser.php` endpoint and control the `user2del` parameter in HTTP requests.

Does an attacker need authentication to exploit this?

It depends on how the application is configured. If `/deluser.php` is accessible without strong access controls, the vulnerability can be exploited by unauthenticated users; otherwise, a low-privileged account might be sufficient.

What is the safest general fix pattern for this issue?

The most robust pattern is to refactor all affected database operations to use prepared statements or parameterized queries, combined with strict server-side validation for the `user2del` parameter and any similar inputs.
