Is this vulnerability remotely exploitable?

Yes. Anyone with network access to the Admidio instance can request the direct URL of an uploaded document, and the server will serve it without enforcing authentication, provided the file path is known.

Does an attacker need an account to exploit this?

Not necessarily. While an authenticated user may more easily obtain file paths via upload responses or the UI, the underlying issue allows any unauthenticated user who knows or can discover a document URL to access it directly over HTTP.

What is the safest general fix pattern?

Move access control from relying on `.htaccess` to explicit application-layer checks by serving uploaded files through controlled download endpoints, and/or adjust the web server configuration to enforce the intended restrictions consistently across environments.
