‼️ Tailscale SSH (Tailworm)

Researchers report that a compromised, SSH-authorized device could gain root on permitted targets via forwarding flaws.

Not unauthenticated RCE. Lab-tested; scope still under review.

Mitigations:
• Tighten SSH access policies
• Disable forwarding if unused (TS_SSH_DISABLE_FORWARDING=1)
• Enable SSH check mode as an added barrier

Tailnet Lock helps limit device enrollment abuse, not root escalation. Tailscale isn't recommending a blanket SSH shutdown.
