Is this vulnerability remotely exploitable over the internet?

Not directly in a default clustered setup. Exploitation typically requires prior compromise of a worker node or the ability to impersonate a legitimate worker communicating with the master.

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

The attacker must have substantial control over at least one worker node, such as shell access, the ability to run arbitrary code, or control over the process that sends serialized data to the master.

What is the safest general fix pattern for this class of vulnerability?

The safest pattern is to avoid deserializing complex, executable object graphs from untrusted sources. Instead, use data-only formats with strict schema validation, whitelisted types, and clear separation between data parsing and code execution.
