CVE-2022-41924Network attack vector

Remote code execution via CSRF

Published Nov 23, 2022 · Updated Apr 22, 2025

Cross-site request forgery in the Tailscale Windows client before 1.32.3 allows remote attackers to execute code via a malicious website. The client exposes a cleartext local TCP API without Host-header verification, allowing DNS rebinding and forged requests that switch the coordination server and trigger malicious URL handling. The attack requires a victim to visit the attacker-controlled website; the resulting coordination-server responses can push executables or install an SMB share, leading to code execution on the Windows node.
