Tailscale Fixes Flaw Allowing Root Access Across Network Servers

Tailscale has issued an update to address security flaws in its built-in SSH server. The vulnerabilities could allow an attacker with access to a compromised device to reach protected root-level files and services on other connected servers. Canadian businesses using the platform should apply updates quickly to prevent unauthorized access across their networks.
