Is this vulnerability remotely exploitable?

It can be, if the application exposes a remote file import or upload interface. In that case, an attacker who can submit crafted files over the network may exploit the arbitrary overwrite. If imports are strictly local, the risk is limited to local users or processes with access to the import mechanism.

What level of access does an attacker need to exploit this issue?

The attacker must be able to supply or control files processed by the Comic Book Reader import feature. They do not necessarily need OS-level access, but they do need logical access to whatever mechanism the application uses to ingest comic book or related files.

What is the safest general fix pattern?

The safest pattern is to enforce strict path normalization and containment. All paths derived from user-controlled data should be resolved against a fixed base directory, and any path that attempts to escape that directory or uses traversal constructs, absolute paths, or symlinks should be rejected outright.
