A vulnerability was found in mod_proxy_cluster. The issue is that the directive should be replaced by the directive as the former does not restrict IP/host access as Require ip IP_ADDRESS would suggest. This means that anyone with access to the host might send MCMP requests that may result in adding/removing/updating nodes for the balancing. However, this host should not be accessible to the public network as it does not serve the general traffic.
