Is this vulnerability remotely exploitable?

Yes. When the EPyT-Flow REST API is network-accessible, an attacker can exploit this issue remotely by sending specially crafted JSON requests that trigger unsafe deserialization and command execution.

What level of access does an attacker need?

The attacker needs the ability to supply JSON input that EPyT-Flow will parse—typically HTTP access to the vulnerable REST endpoints or control over JSON files that the application loads. No local shell access is required.

What is the safest general fix pattern?

Replace the custom `my_load_from_json` deserializer with a data-only parsing approach that maps JSON into predefined, simple data structures. Avoid interpreting fields like `type` as instructions to import or instantiate arbitrary classes, and if polymorphism is required, use an explicit allowlist of safe types.
