Dragonfly is an open source P2P-based file distribution and image acceleration system. Versions prior to 2.1.0 contain a server-side request forgery (SSRF) vulnerability that enables users to force DragonFly2’s components to make requests to internal services that are otherwise not accessible to them. The issue arises because the Manager API accepts a user-supplied URL when creating a Preheat job with weak validation, peers can trigger other peers to fetch an arbitrary URL through pieceManager.DownloadSource, and internal HTTP clients follow redirects, allowing a request to a malicious server to be redirected to internal services. This can be used to probe or access internal HTTP endpoints. The vulnerability is fixed in version 2.1.0.

GHSA-g2rq-jv54-wcpr — Dragonfly vulnerable to server-side request forgery

2026-10-04T05:21:11.953603+00:00

Affected: Go: github.com/dragonflyoss/dragonfly, Go: d7y.io/dragonfly/v2

### Impact There are multiple server-side request forgery (SSRF) vulnerabilities in the DragonFly2 system. The vulnerabilities enable users to force DragonFly2’s components to make requests to internal services, which otherwise are not accessible to the users. One SSRF attack vector is exposed by the Manager’s API. The API allows users to create jobs. When creating a Preheat type of a job, users provide a URL that the Manager connects to (see figures 2.1–2.3). The URL is weakly validated, and so users can trick the Manager into sending HTTP requests to services that are in the Manager’s local network.

```golang func (p *preheat) CreatePreheat(ctx context.Context, schedulers []models.Scheduler, json types.PreheatArgs) (*internaljob.GroupJobState, error) { [skipped] url := json.URL [skipped] // Generate download files var files []internaljob.PreheatRequest switch PreheatType(json.Type) { case PreheatImageType: // Parse image manifest url skipped, err := parseAccessURL(url) [skipped] [skipped] case PreheatFileType: [skipped] } ```

A second attack vector is in peer-to-peer communication. A peer can ask another peer to make a request to an arbitrary URL by triggering the pieceManager.DownloadSource method (figure 2.4), which calls the httpSourceClient.GetMetadata method, which performs the request.

Another attack vector is due to the fact that HTTP clients used by the DragonFly2’s components do not disable support for HTTP redire…
