Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Apache DolphinScheduler versions 3.2.0 up to but not including 3.3.1 are vulnerable, as is the dolphinscheduler-rpc module. An attacker with network access to the Master or Worker nodes can send crafted RPC requests containing a malicious class type, which leads to unsafe deserialization and possible compromise of the system. Upgrade to version 3.3.1, which fixes the issue.
