I might be misreading the code in the filter, but doesn't the filter only block if it is a modification request?

> The Referrer Filter in Apache Sling Security blocks requests without a Referrer or a non-allow listed Referrer. Therefore Referrer filter will also block external CORS requests which rather than using the Referrer, like standard browser requests, use the Origin header. 
> We should therefore enable bypassing the ReferrerFilter for requests containing an Origin header. These requests would need to be separately validated by something else to ensure the Origin is valid.
