Is this vulnerability remotely exploitable?

It can be, if an attacker can remotely influence which APK packages apko consumes—such as through a compromised repository, a typosquatted package, or any mechanism that feeds attacker-controlled package metadata into the build process.

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

The attacker must be able to introduce or control an APK package used by apko. Direct access to the build host is not required if the package source or dependency resolution process can be influenced.

What is the safest general fix pattern for developers?

Enforce strict path confinement by validating that any path derived from external or package-controlled data remains within the intended base directory before performing filesystem operations, and centralize this logic in a reusable, well-reviewed abstraction.
