Is this vulnerability remotely exploitable?

It can be, depending on how the host application exposes archive processing. If users can upload or otherwise supply archives that are passed to `Expand.extractFile` without strong validation, an attacker may exploit the issue remotely through that interface.

What level of access does an attacker need?

The attacker must be able to influence the archive being extracted—such as providing a ZIP as an upload, dependency, plugin, or build artifact. No direct shell or local account access is required if the application itself handles archives on the attacker's behalf.

What is the safest general fix pattern?

The safest pattern is to ensure robust path canonicalization and containment: normalize the target path of each archive entry, verify it remains a descendant of the intended extraction directory, and reject any entry that fails this check. When possible, rely on well-reviewed libraries that implement these guarantees by design.
