Tailscale SSH Vulnerability Allows Root Access via Unix Socket Redirection

A researcher identified flaws in Tailscale that let an attacker with existing SSH access on one node escalate to root privileges and move laterally across the network. Erica Windisch of Cyberdione Labs demonstrated the issues in lab conditions against Tailscale 1.104.2 and Headscale 0.29.5. The core problem stems from privileged operations performed by the tailscaled process when handling Unix socket redirection, granting an ordinary SSH session access to root-only resources. The researcher used the technique to interact with Docker and run elevated commands, and showed that broad access policies allow automated lateral movement in under a second. Additional issues include denial-of-service conditions and bypasses of certain restrictions. Recommendations include reviewing SSH policies and disabling unnecessary socket redirection, noting that Headscale 0.29.5 lacks an independent way to turn the feature off.

LxBox Evolves from VPN Client to Comprehensive Network Traffic Management Ecosystem

LxBox has grown from a personal Android client for sing-box into a full ecosystem spanning mobile, desktop, and router platforms. The project now supports a wide range of VPN and proxy protocols within a single routing framework, allowing users to manage corporate SSL VPNs, home WireGuard connections, and proxy servers together. Key security features include default ingress blocking to prevent unauthorized reverse connections through VPN tunnels and protections against traffic leaks via excluded applications. The developer introduced progressive configuration levels, from one-click WARP setup to advanced JSON editing and AI-friendly documentation. The core sing-box-lx fork ranks among the top sing-box derivatives and powers third-party tools such as the upcoming NekoBox 6. LxBox is available on Google Play, F-Droid, and GitHub, with desktop launcher support for Windows 7 and later, macOS, and Linux.

Securing OpenClaw and Hermes AI Agents on One VPS: Hardening Lessons from Docker, SSH, and Prompt Injection Risks

A detailed case study examines the challenges of running OpenClaw and Hermes AI agents together on a single VPS, connected via an SSH channel with forced commands. The author deployed OpenClaw as an orchestrator handling Telegram messages and Hermes as an executor for heavy tasks inside its own Docker sandbox. Multiple security misconfigurations were discovered, including Docker publishing ports directly to 0.0.0.0, ufw being removed during iptables-persistent installation, and repeated resets of gateway.bind to lan. The built-in security audit revealed a critical issue where Telegram groups allowed arbitrary command execution without an allowlist. Additional risks included context file injection that could propagate through the ACP bridge and UID conflicts caused by cloud image defaults. The experience highlights that AI agents require strict least-privilege controls because they interpret arbitrary text as potential instructions.
