CVE-2026-78321

DJI Drone HTTP Media Server Denial of Service via Connection Pool Exhaustion

Published Aug 24, 2026 CVSS 4.0 · 6 Medium EPSS < 1% KEV · Not listed

Description

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.

Remediation requires a firmware update from the vendor.

Analysis

Technical impact

The HTTP media server on DJI drones fails to enforce limits on connections or request rates, allowing an attacker to repeatedly request a stored media file and consume all connections in the server’s pool. This exhausts legitimate traffic and prevents the DJI Fly application from retrieving photos and videos via QuickTransfer, resulting in a denial of service. The flaw is a connection‑pool exhaustion weakness (CWE-770).

Affected Systems

The vulnerability affects a range of DJI aircraft with firmware versions below specific thresholds: DJI Neo < 01.00.0400, Neo 2 < 01.00.0500, Flip < 01.00.1200, Air 3 < 01.00.1600, Air 3S < 01.00.1400, Avata 2 < 01.00.0400, Avata 360 < 01.00.0300, Mavic 3 < 01.00.1400, Mavic 3 Classic < 01.00.0800, Mavic 3 Pro < 01.01.0700, Mavic 4 Pro < 01.00.0500, Mini 2 < 01.07.0200, Mini 3 < 01.00.0500, Mini 3 Pro < 01.00.0900, Mini 4 Pro < 01.00.1100, and Mini 5 Pro < 01.00.0600. All listed models must apply the vendor‑issued firmware update to remediate.

Risk and Exploitability

The CVSS score of 6.0 indicates a moderate risk profile. EPSS data is unavailable, and the flaw is not listed in the CISA KEV catalog, suggesting limited known exploitation. Attackers must first gain internal network access to the aircraft—typically by physical proximity or compromising the Wi‑Fi network—to send repeated media requests. Once inside, they can exhaust the connection pool, causing a service disruption, but the bug does not grant code execution or data exfiltration capabilities.

OpenCVE Recommended Actions

Apply the vendor‑issued firmware update that limits connection handling on the HTTP media server.
Secure the drone’s internal network by enforcing strong Wi‑Fi credentials, isolating the device from public networks, or applying firewall rules to block unauthorized devices.
Monitor the media server for abnormal connection patterns or sustained high‑rate requests, and investigate any sustained high‑rate activity.
