Is this vulnerability remotely exploitable?

Yes. As described, the vulnerability can be exploited remotely if the IOPaint File Manager endpoints are exposed over the network and accept user-controlled `filename` parameters.

Does an attacker need authenticated access to exploit this?

That depends on how the application is deployed and configured. If the file retrieval functionality is available to unauthenticated users, exploitation can be anonymous; if it is behind login, attackers would need whatever level of access is required to reach that endpoint.

What is the safest general fix pattern for this issue?

Implement strict path handling by canonicalizing requested file paths, enforcing that they remain within a configured base directory, and rejecting any request that attempts to escape that directory. Where possible, replace direct filename parameters with indirect identifiers that are mapped to known-safe locations.
