Description
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.
