Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, the code in the scheduler for downloading a tiny file is hard coded to use the HTTP protocol, rather than HTTPS. This means that an attacker could perform a Man-in-the-Middle attack, changing the network request so that a different piece of data gets downloaded. This vulnerability is fixed in 2.1.0.

CVE-2025-59410 [MEDIUM] CWE-311 DragonFly's tiny file download uses hard coded HTTP protocol
DragonFly's tiny file download uses hard coded HTTP protocol
### Impact
The code in the scheduler for downloading a tiny file is hard coded to use the HTTP protocol, rather than HTTPS. This means that an attacker could perform a Man-in-the-Middle attack, changing the network request so that a different piece of data gets downloaded. Due to the use of weak integrity checks (TOB-DF2-15), this modification of the data may go unnoticed.
```golang
// DownloadTinyFile downloads tiny file from peer without range.
func (p *Peer) DownloadTinyFile() ([]byte, error) {
ctx, cancel := context.WithTimeout(context.Background(),
downloadTinyFileContextTimeout)
defer cancel()
// Download url:
http://${host}:${port}/download/${taskIndex}/${taskID}?peerId=${peerID}
targetURL := url.URL{
Scheme:
}
