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.\n\n* An attacker within BLE range recovers the Wi-Fi SSID and PSK in cleartext, and can then join the drone's network \n* 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.\n* The credentials do not change between sessions unless the operator manually resets the Wi-Fi settings, so one capture stays valid indefinitely\n* 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\n* A BLE sniffer and presence during one normal DJI Fly connection are needed\n\nAffected 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.\n\nRemediation requires a firmware update from the vendor. There is no user-side mitigation that fully addresses the vulnerability without upgrading.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"abyssal","depthScore":64,"depthScoreParts":{"impact":51.7,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[{"seq":220751,"id":"CVE-2026-77812","ts":1792026743025,"field":"cvss","old":null,"new":"9.4"},{"seq":220750,"id":"CVE-2026-77812","ts":1792026743025,"field":"severity","old":"none","new":"critical"}]}
