What is CVE-2026-78306?
CVE-2026-78306 is a high-severity authentication bypass vulnerability in DJI Air 3, published on 24 Aug 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
DJI drones expose an unauthenticated DUML command interface over Bluetooth that allows an attacker within Bluetooth range to modify Wi-Fi configuration parameters, including the SSID, PSK, MAC address, regulatory country code, and wireless channel. An attacker can overwrite the Wi-Fi PSK with a known value and connect to the drone's internal Wi-Fi network, potentially gaining access to the flight control interface and issuing flight commands. Crafted DUML commands can also disable or restart the Wi-Fi and Bluetooth interfaces, disconnect Wi-Fi clients, or reset wireless configuration, resulting in a denial-of-service condition that can disrupt the operator's wireless control, video, and telemetry connections during flight.
Affected models are DJI Neo until 01.00.0400, DJI Neo 2 until 01.00.0500, DJI Flip until 01.00.1200, DJI Air 3 until 01.00.1600, DJI Air 3S until 01.00.1400, DJI Avata 2 until 01.00.0400, DJI Avata 360 until 01.00.0300, DJI Mavic 3 until 01.00.1400, DJI Mavic 3 Classic until 01.00.0800, DJI Mavic 3 Pro until 01.01.0700, DJI Mavic 4 Pro until 01.00.0500, DJI Mini 2 until 01.07.0200, DJI Mini 3 until 01.00.0500, DJI Mini 3 Pro until 01.00.0900, DJI Mini 4 Pro until 01.00.1100, and DJI Mini 5 Pro until 01.00.0600.
Remediation requires a firmware update from the vendor.
