> 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.
There is some weaselly language.

I fully understand being carefully worded when you need serious brain power just to figure out every claim in the logorrhea
Quick reminder that in recent months Tailscale has had issues with age-old classic vulnerabilities such as input validation.
The problem with Tailscale is twofold.
First their attack surface is too big. They continuously shoehorn new features into the product.
Second they don't appear to do regular deep-dive code audits and instead they appear to rely mostly on the goodwill of third-parties to poke at select areas of their code as and when those third-parties feel like it. Hence simple vulnerabilities such as input validation keep on popping up.
Fancy SOC2 certificates are not the same thing. That's just dogfood for the corporate auditors.
At $work we are busy working on removing Tailscale. The bells and whistles of Tailscale sure are attractive candy, but we simply can't overlook the security risk of what has become a bloated product.
Good idea to set up automatic updates for the tailscale client though.
My question to those who kept praising Tailscale and making fun of good old plain SSH: how do you like your state backdoor --excuse me, I mean bug-- in Tailscale now?
