Summary
Vulnerability reported (CVE-2026-77812). Risk of unauthorized operations or information disclosure.
Original description
The description as published by the source.
DJI drones transmit DUML (DJI Universal Markup Language) protocol messages over BLE (Bluetooth Low Energy) without encryption. When a client attempts to connect to the drone over Wi-Fi, or when the drone is switched to QuickTransfer mode, the DJI Fly application exchanges DUML messages with the drone over BLE, including the Wi-Fi credentials. An attacker within BLE range can passively sniff this traffic and recover the credentials in cleartext, including the drone's Wi-Fi PSK, SSID, and trusted identifier UUID. Obtaining these credentials allows the attacker to join the drone's internal Wi-Fi network, interact with network services exposed by the drone, and decrypt Wi-Fi traffic exchanged between the drone and the legitimate user.
- An attacker within BLE range recovers the Wi-Fi SSID and PSK in cleartext, and can then join the drone's network
- The same capture also exposes the session UUID identifier, which is the only thing the drone uses to tell a trusted client from an unknown one, so the attacker can replay it and skip the physical confirmation of new connected devices.
- The credentials do not change between sessions unless the operator manually resets the Wi-Fi settings, so one capture stays valid indefinitely
- The attack is fully passive, with nothing transmitted and no connection made, so neither the operator nor the drone has any indication the session was observed
- A BLE sniffer and presence during one normal DJI Fly connection are needed
