# MoviePilot: unsafe deserialization in workflow fork endpoint allows remote attack

MoviePilot up to 3.1.2 deserializes attacker-supplied data in the Workflow Fork Endpoint, in WorkflowExecutor.restore_context. A remote attacker can send a crafted request to trigger the deserialization, and a public exploit has been disclosed.

_Summary, check and fix written by a model from the sources; labelled as such._

## How to check

- Check the installed MoviePilot version and whether it is `3.1.2` or earlier.
- Confirm whether the Workflow Fork Endpoint is reachable from the network (unknown from sources whether it is enabled by default).

## Fix

- MoviePilot: upgrade to `3.1.3` (patch commit 6034dcc880c13079aeb398dbe32c346ebcd3a6d2).
