Is this vulnerability remotely exploitable?

It can be, if a service accepts checkpoints or model files from remote users or external sources and then calls `torch.load(..., weights_only=True)` on them. In that case, a remote attacker could potentially trigger the vulnerability by supplying a malicious file.

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

The attacker needs the ability to influence or control the checkpoint file being loaded. This might occur through direct file uploads, access to shared storage, poisoned model repositories, or compromised artifact pipelines used by training or inference jobs.

What is the safest general fix pattern?

The safest pattern is to avoid loading untrusted checkpoints with generic pickle-based mechanisms. Use strictly defined, non-executable formats for model weights, enforce schema validation before loading, and, when untrusted artifacts must be processed, perform the operation in an isolated, low-privilege environment.
