Official description

Projects using the SUSE Virtualization (Harvester) environment may expose the OS default ssh login password if they are using the 1.5.x or 1.6.x interactive installer to either create a new cluster or add new hosts to an existing cluster. The environment is not affected if the PXE boot mechanism is utilized along with the Harvester configuration setup.

The underlying weakness: Initialization of a Resource with an Insecure Default
