CVE-2026-9773Network attack vector

Authenticated code execution via ToggleState system call

Published Jun 24, 2026 · Updated Jun 24, 2026

OS command injection in Unraid OS before 7.3.0 allows remote authenticated users to execute arbitrary code through the WebGUI. ToggleState.php passes a user-supplied string to a system call without proper validation, allowing injected commands to run as www-data. Valid WebGUI authentication is required; successful exploitation grants code execution with the web server account's privileges.
