Every security hole ? No, of course not.

But things like insecure argument handling are low-hanging fruit for security auditors.

Insecure argument handling is not like the more advanced subtle vulnerabilities that we are seeing in some LLM-assisted reports these days. Insecure argument handling is 1990's security.

The fundamental problem remains that Tailscale has too many new "features" being added to it the whole time. New features means a whole bunch new code. Which increases bloat and exponentially increases the attack surface.

It would be really nice if you could stop shoehorning in every new feature you can think of. Remove some of the existing ones that don't really need to be there. And get your codebase back to a more focused state, get back to your roots as a VPN product.

Stop trying to be all things to all men, as the old saying goes.

It appears that you have a major bone to pick with Tailscale and direct replies to your concerns do not seem to matter. They have a good security track record and are extremely widely deployed. I don’t see the evidence for your assertions that it is bloated and insecure.
