CVE-2026-78321: CWE-770 Allocation of Resources Without Limits or Throttling in DJI Neo
Description
CVE-2026-78321 is a denial-of-service vulnerability in the HTTP media server of multiple DJI drone models. The server does not enforce limits on incoming connections or request rates, allowing an attacker on the drone's internal network to exhaust connection resources by repeatedly requesting stored media files. This prevents legitimate requests and blocks the DJI Fly app from retrieving photos and videos in QuickTransfer mode. A firmware update from DJI is required to remediate this issue.

Technical Analysis
The HTTP media server on DJI drones lacks sufficient limits on incoming connections and request rates. An attacker with internal network access can repeatedly request stored media files, exhausting the server's connection pool. This causes a denial of service, preventing the DJI Fly application from accessing media via QuickTransfer. Affected models include DJI Neo, Neo 2, Flip, Air 3, Air 3S, Avata 2, Avata 360, Mavic 3 series, Mini 2, Mini 3 series, Mini 4 Pro, and Mini 5 Pro up to specified firmware versions. Remediation requires a firmware update from the vendor.
Potential Impact
An attacker on the drone's internal network can cause a denial of service by exhausting the HTTP media server's connection pool. This prevents legitimate media retrieval requests from the DJI Fly application in QuickTransfer mode, disrupting normal drone media operations.
Mitigation Recommendations
A firmware update from DJI is required to fix this vulnerability. Users should apply the official firmware updates once released to address this issue. Until then, limiting access to the drone's internal network can reduce exposure.
