> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Aldrin Piri
> Assignee: Andy LoPresto
> Priority: Major
>
> The host header whitelisting evaluation is only done when NiFi is configured
> in secure mode, determined by the setting of an HTTPS port. (see
> https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-jetty/src/main/java/org/apache/nifi/web/server/JettyServer.java#L161

> However, in the case where both are enabled, the HTTP port is not enumerated
> in possible combinations and explicit inclusions of a given socket that would
> be HTTP is stripped via

> It is possible that concurrently running HTTP and HTTPS no longer makes
> sense, in which case we could evaluate the relevant properties and prevent
> startup for an unintended configuration. Alternatively, we would need to
> adjust the custom hostname interpretation to also include consideration for
> the HTTP port.
