| الوصف | Webhook SSRF (Server-Side Request Forgery)
**Evidence:**
```go
req, err := http.NewRequest(webhook.Method, webhook.Url, body)
// ...
resp, err := client.Do(req) // No URL validation, no internal network blocking
```
Admin-configured webhook URLs are fetched without any restriction on target address. No SSRF protections are in place.
**Attack scenario:** An attacker who gains org-admin access configures a webhook URL pointing to `http://x.x.x.x/latest/meta-data/` (AWS metadata endpoint) or internal services, exfiltrating cloud credentials or scanning internal infrastructure.
**Fix:** Validate webhook URLs against a denylist of private/reserved IP ranges. Use a dedicated HTTP client that resolves DNS and blocks connections to internal addresses.
