## Overview

Deserialization of Untrusted Data vulnerability in Apache DolphinScheduler RPC module.

This issue affects Apache DolphinScheduler: 

Version >= 3.2.0 and < 3.3.1.

Attackers who can access the Master or Worker nodes can compromise the system by creating a StandardRpcRequest, injecting a malicious class type into it, and sending RPC requests to the DolphinScheduler Master/Worker nodes.
Users are recommended to upgrade to version [3.3.1], which fixes the issue.

## Affected

- `dolphinscheduler >= 3.2.0, < 3.3.1`

## Remediation

Upgrade past the affected range:

- `dolphinscheduler 3.3.1`
