CVE-2026-71913Network attack vector

Authenticated root command execution via restorekey concatenation

Published Aug 24, 2026 · Updated Aug 26, 2026

OS command injection in six DrayTek VigorAP models allows remote authenticated users to execute arbitrary commands with root privileges. The upload_settings.cgi handler concatenates an insufficiently filtered restorekey field into a shell command. Administrative web-interface credentials are required, and DrayTek states that no practical attack path has been demonstrated in deployed environments.
