Is this vulnerability remotely exploitable over the network?

Yes. Any user who can reach the SillyTavern chat or avatar endpoints over the network and authenticate can exploit the flaw by sending crafted requests, without needing local filesystem access.

Does an attacker need special privileges to exploit this issue?

Only standard authenticated user access is required. The issue does not depend on administrative rights, but its effects are typically limited to the authenticated user's data root.

What is the safest general fix pattern for this vulnerability class?

The safest pattern is to avoid using raw user-supplied path segments for filesystem access at all. Instead, map user choices to predefined, server-controlled filenames or IDs, and enforce canonical path checks that guarantee the final path remains inside a designated directory.
