CVE-2026-78578

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.

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