What happened

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

About this data

This record was ingested from a data source. Retrieved: Nov 6, 2026, 13:21 UTC. Ingestion is not an independent editorial investigation.

NVD status: Deferred. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.
