Tailscale says its security and engineering teams, aided by outside specialists, have found multiple vulnerabilities in Tailscale SSH, most involving privilege escalation that could let an already-authorized user act beyond their configured permissions. The company has fixed most issues and is targeting a patched client release by the end of Tuesday, October 27, while continuing to assess remaining findings.

Security researchers at Cyberdione Labs identified 11 vulnerabilities, collectively dubbed Tailworm, in Tailscale 1.104.2 and self-hosted headscale v0.29.5 that remain unpatched. The most severe flaw lies in Tailscale's embedded SSH server, where unix-socket forwarding bugs could let an authorized device gain root-level code execution, steal enrollment keys, or delete arbitrary root files on a target machine. Founder Erica Windisch said the issues were confirmed in a lab using unmodified released software and were disclosed publicly to speed up fixes.
