TypeBot versions 3.16.0 and earlier have an improper authentication vulnerability in the WhatsApp Cloud API webhook endpoint. The endpoint does not verify the x-hub-signature-256 HMAC signature that Meta includes in webhook deliveries. Because the webhook URL exposes workspaceId and credentialsId in the path, which are logged and visible in multiple places, an unauthenticated attacker can send spoofed webhook messages. This can trigger bot flows, consume API resources, and interact with external services using the workspace owner's credentials. The issue is fixed in version 3.17.0.
