Is this vulnerability remotely exploitable?

It can be, if a remote user can upload or otherwise provide zip files that the application extracts using pf4j. In purely local or tightly controlled scenarios, the risk is reduced but still present if archives can be influenced.

What level of access does an attacker need?

An attacker needs the ability to control the contents of a zip file processed by `Unzip.extract()`, such as through plugin upload features, extension repositories, automated update feeds, or any integration that ingests external archives.

What is the safest general fix pattern?

Normalize the path derived from each zip entry and enforce that it stays within the intended extraction directory before writing. Reject any entries that produce paths outside the allowed root, and avoid using zip entry names directly without these checks.
