A server-side request forgery vulnerability in Apioo Fusio 8.8.3 allows authenticated consumer-role users to make the server issue HTTP requests to internal network addresses by registering a webhook URL pointing to an internal host.

When the registered event fires, the server issues an HTTP POST to the attacker-supplied internal URL.
