  > Most of the Tailscale SSH issues we've identified concern privilege escalation. In some circumstances, someone already authorized to connect over Tailscale SSH may be able to perform actions beyond the permissions of their configured local user, including potentially gaining elevated privileges.

"Most"? "In some circumstances"? Makes me think that they could also be investigating a full on unauthorized connection issue, or am I reading too much into it?

I think they're just writing cautiously because they're midway through the investigation and don't want to give false confidence. Doesn't seem worth reading too much into it until they provide a more thorough write up.

A security researcher colleague of mine was/is exploring an unauthenticated avenue along this line. I don’t have any update, she told me she didn’t feel comfortable exposing information to anyone other than Tailscale staff until she’s confident in what she found or didn’t.
