CVE-2026-78251Network attack vector

Storage exhaustion via hard-coded FTP credentials

Published Aug 24, 2026 · Updated Aug 24, 2026

Hard-coded FTP credentials in affected DJI drone firmware allow remote attackers to access and overwrite persistent onboard storage. The onboard FTP service accepts credentials shared across models and applies no file-size, file-count, or aggregate-storage limit to uploads under /blackbox/upgrade/. Internal-network or USB RNDIS access is required; exhaustion prevents flight-record, log, and telemetry writes, while uploaded files survive reboot and factory reset.
