On version 3.0.0 through 3.1.1, Apache DolphinScheduler's python gateway suffered from improper authentication: an attacker could use a socket bytes attack without authentication.

For users who use version 3.0.0 to 3.1.1, you can turn off the python-gateway function by changing the value `python-gateway.enabled=false` in configuration file `application.yaml`.
