Cleartext BLE Exposure of Wi-Fi Credentials in DJI Drone Firmware

IdentifiersCVE-2026-77812CWE-311· Missing Encryption of Sensitive Data

CVE-2026-77812 is an information disclosure vulnerability in multiple DJI drone models in which DUML protocol messages exchanged over Bluetooth Low Energy during Wi-Fi connection setup and QuickTransfer operations are transmitted without encryption. Sensitive onboarding data, including the drone’s Wi-Fi SSID, pre-shared key, and a trusted client identifier UUID, can be recovered in cleartext by a nearby passive observer. Because the trusted identifier is used by the drone to distinguish known clients, capture of this value can enable replay to bypass physical confirmation normally required for new connected devices. The exposed Wi-Fi credentials persist across sessions unless the operator manually resets Wi-Fi settings, allowing a single interception to remain useful over time. Affected models include DJI Neo through 01.00.0400, DJI Neo 2 through 01.00.0500, DJI Flip through 01.00.1200, DJI Air 3 through 01.00.1600, DJI Air 3S through 01.00.1400, DJI Avata 2 through 01.00.0400, DJI Avata 360 through 01.00.0300, DJI Mavic 3 through 01.00.1400, DJI Mavic 3 Classic through 01.00.0800, DJI Mavic 3 Pro through 01.01.0700, DJI Mavic 4 Pro through 01.00.0500, DJI Mini 2 through 01.07.0200, DJI Mini 3 through 01.00.0500, DJI Mini 3 Pro through 01.00.0900, DJI Mini 4 Pro through 01.00.1100, and DJI Mini 5 Pro through 01.00.0600.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows a nearby attacker to recover the drone’s Wi-Fi credentials and trusted client identifier without active interaction, alerts, or visible side effects. With those values, the attacker can join the drone’s internal Wi-Fi network, replay the trusted identifier to avoid new-device confirmation, access or interact with services exposed on the drone-side network, and decrypt Wi-Fi traffic exchanged between the drone and the legitimate operator. Because the attack is passive and the captured credentials remain valid until Wi-Fi settings are reset, compromise can enable persistent unauthorized access and ongoing interception opportunities.

Mitigation

If you can’t patch tonight, do this now.

No complete user-side mitigation is available short of installing the vendor firmware update. Operational exposure can be reduced by minimizing use of BLE-assisted connection workflows such as DJI Fly Wi-Fi setup and QuickTransfer in the presence of untrusted nearby parties, and by resetting Wi-Fi settings after suspected exposure to invalidate previously captured credentials. These measures only reduce risk and do not fully remediate the underlying flaw.

Remediation

Patch, then assume compromise.

Apply the vendor firmware update for all affected DJI drone models. Devices should be upgraded to firmware versions newer than the affected versions identified for each model. After updating, operators should reset Wi-Fi settings where feasible so previously exposed credentials and trusted identifiers are no longer valid.

CVE-2026-77812 - Cleartext Exposure of DJI Drone Wi-Fi Credentials via BLE

A critical information disclosure vulnerability in DJI drones where unencrypted BLE DUML messages expose Wi-Fi credentials and a trusted session UUID in cleartext, enabling a nearby attacker to passively recover credentials, join the drone's Wi-Fi network, replay the UUID to bypass new-device confirmation, and decrypt traffic.
