CVE-2021-44319Public exploit

Flight-control interruption via Wi-Fi deauthentication

Published Sep 4, 2026 · Updated Sep 4, 2026

Wi-Fi deauthentication in Parrot AR.Drone 1 and AR.Drone 2 allows remote attackers to disconnect the drone from its controller. The platform accepts unauthenticated IEEE 802.11 deauthentication traffic, terminating the control link while the aircraft is in flight. Exploitation requires Wi-Fi radio proximity and can interrupt piloting and video connectivity, with no reported persistent device damage.
