CVE-2025-59346Network attack vector

Internal service access via weak URL validation

Published Sep 17, 2025 · Updated Sep 17, 2025

SSRF in dragonflyoss Dragonfly before 2.1.0 allows remote attackers to access internal HTTP services through crafted source URLs. The Manager's CreatePreheat path weakly validates a supplied URL, pieceManager.DownloadSource accepts arbitrary peer URLs, and HTTP clients follow redirects to internal destinations. Network access to the Manager API or participation as a peer is sufficient to make Dragonfly probe or reach otherwise inaccessible HTTP endpoints.
