Servers fail to validate the "Origin" header on incoming connections, which may allow DNS rebinding attacks. DNS rebinding is a method of bypassing the Same-Origin Policy to interact with services on a private network from a remote browser.
Recommendations
Update to version 0.25.0 or later and use the
--allowed-hosts or --allowed-origins flags to specify permitted hosts and origins at server startup.Exploitability
