Is this vulnerability remotely exploitable?

It can be, depending on how GuardDog is integrated. If an attacker can get a malicious package into a workflow where GuardDog automatically scans dependencies (such as a CI pipeline consuming public PyPI), they may be able to exploit the vulnerability without direct access to the host.

What level of access does an attacker need?

The attacker must be able to influence which package GuardDog scans—typically by publishing or supplying a crafted package that a user or automated system runs GuardDog against. They do not necessarily need shell access to the machine where GuardDog runs.

What is the safest general fix pattern?

The most robust fix is to normalize and validate all archive member paths before extraction, enforcing that the final resolved path remains within the intended extraction root, and rejecting any entry that would escape that directory.
