That isn't even remotely related the post and Monterey is over a year old.

The systems you are trying to SSH to are using outdated host keys, you need to actually update to get security fixes, it will regenerate host keys.

You shouldn't be worried about this CVE, it sounds like you have quite a few years of CVE's you've neglected to patch anyways.

No you don't. rsa-sha2-256 and rsa-sha2-512 are still enabled by default and can use the same key.

The reason it triggered my question is they had to do something similar to get the exploit to work (add +ssh-rsa to putty). Thanks, though, for the thoughtful reply.
