Dragonfly is an open source P2P-based file distribution and image acceleration system. Prior to 2.1.0, The Manager disables TLS certificate verification in HTTP clients. The clients are not configurable, so users have no way to re-enable the verification. A Manager processes dozens of preheat jobs. An adversary performs a network-level Man-in-the-Middle attack, providing invalid data to the Manager. The Manager preheats with the wrong data, which later causes a denial of service and file integrity problems. This vulnerability is fixed in 2.1.0.

- GHSA-98x5-jw98-6c97Dragonfly's manager makes requests to external endpoints with disabled TLS authentication2025-09-17ghsa · osvUS
### Impact The Manager disables TLS certificate verification in two HTTP clients (figures 3.1 and 3.2). The clients are not configurable, so users have no way to re-enable the verification. ```golang func getAuthToken(ctx context.Context, header http.Header) (string, error) { [skipped] client := &http.Client{ Timeout: defaultHTTPRequesttimeout, Transport: &http.Transport{ TLSClientConfig: &tls.Config{InsecureSkipVerify: true}, }, } [skipped] } ``` A Manager processes dozens of preheat jobs. An adversary performs a network-level Man-in-the-Middle attack, providing invalid data to the Manager. The Manager preheats with the wrong data, which later causes a denial of service and file integrity problems. ### Patches - Dragonfy v2.1.0 and above. ### Workarounds There are no effective workarounds, beyond upgrading. ### References A third party security audit was performed by Trail of Bits, you can see the [full report](https://github.com/dragonflyoss/dragonfly/blob/main/docs/security/dragonfly-comprehensive-report-2023.pdf).
