Rails Active Storage has a possible DoS vulnerability when in proxy mode via Range requests

Impact When serving files through Active Storage's Blobs::ProxyController, the controller loads the entire requested byte range into memory before sending it. A request with a large or unbounded Range header e.g. bytes=0- could cause the server to allocate memory proportional to the file size,...
