files from a master/leader node using an HTTP API which accepts a file name. However, Solr did not validate the
file name, hence it was possible to craft a special request involving path traversal, leaving any file readable
to the Solr server process exposed. Solr servers protected and restricted by firewall rules and/or authentication
would not be at risk since only trusted clients and users would gain direct HTTP access.");
