CVE-2026-78255 DJI Drone HTTP Media Server Allows Unauthenticated Access to Stored Media

What is CVE-2026-78255?

CVE-2026-78255 is a high-severity missing authorization vulnerability in DJI Air 3, published on 24 Aug 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

Official description

The HTTP media server running 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.

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.
