How broadly exploitable is this vulnerability?

Any party with network access to the vulnerable Blinko instance and the file server endpoint can potentially exploit this issue, assuming the endpoint is not protected by additional authentication or network controls. It does not inherently require a valid user account.

What level of access does an attacker need?

The attacker needs the ability to send HTTP requests to the file server endpoint. If the endpoint is exposed over the internet or to untrusted networks and lacks authentication, this effectively makes the vulnerability remotely exploitable by unauthenticated users.

What is the safest general fix pattern?

The safest pattern is to avoid using raw client-supplied paths altogether and instead map validated identifiers to known locations on disk. Additionally, implement canonicalization and strict base-directory checks, and ensure that sensitive directories like backups are never directly exposed via HTTP endpoints.
