Is this vulnerability remotely exploitable?

Yes. Any remote user with network access to the Initiative instance can exploit the vulnerability if they know or can discover URLs under the `/uploads/` directory, without needing an account.

Does exploitation require authentication or special privileges?

No. The core issue is that uploaded files are served without authentication or authorization checks. An unauthenticated user, including one in an incognito session, can access files directly if they have the link or can guess the path.

What is the safest general fix pattern?

The safest approach is to remove direct public access to the upload directory and ensure that all file downloads go through an application layer that performs robust authentication and context-aware authorization. Additionally, storing uploads outside the public web root and only streaming them via controlled endpoints reinforces this pattern.
