CVE-2026-78321

MEDIUMCVSS 6/10

Last modified

CVE-2026-78321 is a medium-severity vulnerability rated 6/10 on the CVSS scale. 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. 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.
