Is this vulnerability remotely exploitable?

Yes. As described, a remote attacker with network access to the MiniCMS instance can attempt to exploit the issue if the admin interface is reachable and authentication checks are weak or missing.

Does an attacker need valid credentials to exploit this?

Not necessarily. Because the root issue is improper authentication, some or all code paths in /mc-admin/post-edit.php may be accessible without valid credentials. The exact requirement depends on how the site is configured and which checks are missing.

What is the safest general fix pattern?

Introduce a centralized authentication and authorization mechanism that is applied to all administrative endpoints, including the Article Handler, and ensure every request validates a server-side session or token tied to a properly authenticated user.
