Vulnerability from github – Published: 2026-06-19 22:10 – Updated: 2026-06-19 22:10Lokka versions prior to 2.1.2 constructed Azure Resource Manager request URLs using direct string concatenation with user-controlled path input. Specially crafted path values could alter URL authority parsing and cause Azure Resource Manager bearer tokens to be sent to an unintended host. Version 2.1.2 fixes the issue by validating Azure paths before token acquisition and constructing Azure Resource Manager URLs with the standard URL API while preserving the expected management.azure.com host.

Vulnerability from github – Published: 2025-09-17 19:27 – Updated: 2025-09-26 16:16Impact
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.
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 redirects. This configuration means that an HTTP request sent to a malicious server may be redirected by the server to a component’s internal service.
Patches
- Dragonfy v2.1.0 and above.
Workarounds
There are no effective workarounds, beyond upgrading.

CAPEC-664: Server Side Request Forgery
An adversary exploits improper input validation by submitting maliciously crafted input to a target application running on a server, with the goal of forcing the server to make a request either to itself, to web services running in the server’s internal network, or to external third parties. If successful, the adversary’s request will be made with the server’s privilege level, bypassing its authentication controls. This ultimately allows the adversary to access sensitive data, execute commands on the server’s network, and make external requests with the stolen identity of the server. Server Side Request Forgery attacks differ from Cross Site Request Forgery attacks in that they target the server itself, whereas CSRF attacks exploit an insecure user authentication mechanism to perform unauthorized actions on the user's behalf.
