CVE-2026-78578

Summary

Tapo C120 v1 and C200 v5 do not enforce authentication for do method HTTPS onboarding connect actions after initial setup.  An unauthenticated adjacent attacker can submit unauthorized wireless configuration parameters, causing the camera to attempt connection to a different network.

Successful exploitation disconnects the camera from its intended wireless network, making it unreachable on its management address, resulting in a denial-of-service condition.
