New firmware (2.30.181.0110.2018)?

Hi Guys! Tonight my WDMyCloud has received new firmware: 2.30.181.0110.2018. Everything would be okay, but I can not find any information about the new firmware anywhere. I’m a little worried.

Any suggestions?

Resolved security vulnerability (CVE-2017-17560) - Unauthorized access to multipart
upload functionality.

For the past week or more, on startup, MyCloud announces downloading firmware update, download successful, installing firmware update, update successful. Each day it “successfully” installs firmware 2.30.181.0110.2018. Over and over and over. Apparently no installation is successful. How do I turn off the auto update?
