Snipe-IT: Chained Information Disclosure and IDOR Leads to Full EULA File Takeover

Impact

An attacker can completely bypass file-name randomization security and without authorization download confidential, signed EULA files belonging to any other user across the application.

Steps to Reproduce:

1. Log in as a restricted user.
2. Send a GET request to /api/v1/users/{target_id}/eulas (where target_id belongs to a restricted/denied user).
3. Observe the response leaks the secret EULA filename (e.g., eula-xxx.pdf).
4. Attempt to access this file via the main route: GET /stored-eula-file/{filename} (This will correctly return 403 Forbidden).
5. Now, access the file via the vulnerable profile route: GET /account/stored-eula-file/{filename}.
6. Observe that the server returns a 200 OK and successfully downloads the target user's secret EULA file.
