Is this vulnerability remotely exploitable?

It can be, depending on how Boltz is deployed. If an attacker can remotely upload or synchronize files into directories that Boltz reads from—such as through web interfaces, shared network drives, or automated ingestion pipelines—then exploitation can be triggered without direct local access.

What level of access does an attacker need?

The attacker needs the ability to create or modify molecule data files in locations that Boltz will process. This could be local user access on the same system, write access to a shared directory, or access to any upstream system that feeds files into Boltz.

What is the safest general fix pattern?

The most robust approach is to stop using pickle for untrusted or semi-trusted data and switch to a data-only serialization format with strict schema validation. In parallel, limit input directories to trusted, non-user-writable locations and ensure Boltz runs with minimal privileges.
