CVE-2025-59410Network attack vector

File substitution via plaintext tiny-file downloads

Published Sep 17, 2025 · Updated Sep 17, 2025

Missing transport encryption in dragonflyoss Dragonfly before 2.1.0 allows man-in-the-middle attackers to substitute downloaded files. Peer.DownloadTinyFile constructs each tiny-file URL with a hard-coded http scheme, sending the request in plaintext instead of using HTTPS. Exploitation requires control of the network path, and weak integrity checking lets substituted content pass to a peer without detection.
