CVE-2026-41446

critical · 9.2

Snap One WattBox 800 and 820 series firmware versions prior to 2.10.0.0 contain undisclosed diagnostic HTTP endpoints that require only the device MAC address and service tag for authentication, both of which are printed in plaintext on the physical device label. Attackers with access to the device label or documentation containing these values can authenticate to the several endpoints and execute arbitrary commands as root on the device.
