Authenticated internal-service access via unvalidated webhook URL
Published Mar 7, 2026 · Updated Mar 7, 2026
Server-side request forgery in FFmate 2.0.15 and earlier allows remote authenticated users to reach internal services via webhooks. The fireWebhook function passes each stored webhook.URL directly to http.NewRequest and client.Do without validating its destination. Low-privilege API access can create a webhook and trigger an event, making the server send POST requests to loopback or internal network services.
