Is this vulnerability remotely exploitable?

It can be, depending on how `checkpoint_dir` is sourced. If remote users can influence configuration, request parameters, or job definitions that set `checkpoint_dir`, then the issue becomes remotely exploitable. If only local administrators can change it, exploitation is limited to those with local or administrative access.

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

An attacker needs the ability to control or significantly influence the value passed into `OfflineACE.run` as the checkpoint directory, either directly via an exposed interface or indirectly via configuration files or orchestration systems that the application trusts.

What is the safest general fix pattern for developers?

The safest pattern is to canonicalize all checkpoint paths, enforce that the resolved path resides under a single trusted base directory, and avoid accepting fully arbitrary paths from untrusted sources. Prefer selecting from predefined storage locations or generating internal subpaths rather than using raw user-provided filesystem paths.
