I gather the bug allows people you've explicitly authorized to ssh into some account on your machine, to access more than that account can. So if you only use ssh yourself, or only give ssh keys for users with sudo, or only to people you trust not to exploit this, or if other vulnerabilities allow local shell users to escalate, or if you only use tailscale for port forwarding, then you're unaffected. Arguably even less exposed than a public openssh instance, though I can't say I have any issue doing that
