Low risk4th percentile - higher than 4% of all known CVEs
Summary
DJI drones expose an unauthenticated DUML command interface over Bluetooth, allowing an attacker within range to modify Wi-Fi parameters, including SSID, PSK, MAC address, country code, and channel. This can lead to drone control takeover or DoS.
Risk Assessment
An attacker can gain access to the drone's internal Wi-Fi network, take over flight control, or disrupt operator connectivity, posing a serious security threat.
Recommendation
Update the drone firmware to the latest version provided by the vendor.
Other vulnerabilities in DJI drones
See all- CVE-2026-78251Critical
DJI drones contain an FTP service with hardcoded credentials shared across affected models, allowing authenticated users to upload files without limits and overwrite files in **/blackbox/upgrade/**. An attacker with network or USB RNDIS access can exhaust storage, preventing flight records and firmware updates. Uploaded files persist across reboot and factory reset.
- CVE-2026-77812Critical
DJI drones transmit DUML protocol messages over BLE without encryption. During Wi-Fi client connection or QuickTransfer mode, the DJI Fly app exchanges Wi-Fi credentials (PSK, SSID, UUID) over BLE. An attacker within BLE range can passively sniff this traffic and recover the credentials in cleartext.
- CVE-2026-78321Medium
The HTTP media server on DJI drones does not enforce sufficient limits on incoming connections or request rates. An attacker with access to the drone's internal network can exhaust the server's connection pool by repeatedly requesting a stored media file, preventing the server from handling legitimate requests and causing a denial of service that prevents the DJI Fly application from retrieving photos and videos from the aircraft in QuickTransfer mode. Remediation requires a firmware update from the vendor.
- CVE-2026-78255High
The HTTP media server on DJI drones serves stored photos and videos through the `/v2` endpoint without authenticating the requesting client. Filenames follow a predictable pattern, allowing an attacker who joins the drone's internal network to enumerate valid filenames and exfiltrate stored photos and videos. The exposed media may reveal sensitive information, including private locations, property, travel history, identifiable individuals, and the operator's routines.
Original NVD description (English source)
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.
