Summary
TDuck survey form through version 5.3 fails to validate webhook URLs or verify form ownership in WebhookConfigController. Authenticated attackers can attach webhooks to other users' forms and exfiltrate submissions to arbitrary external or internal addresses.
Risk Assessment
Form submission data may leak to unauthorized recipients, causing confidentiality breaches and potential legal consequences. Attackers could also use webhooks to probe internal resources.
Recommendation
Upgrade TDuck to a version later than 5.3 that includes webhook URL validation and form ownership verification. Until then, restrict webhook configuration to trusted users.
