   @chatman I am trying to figure out if the following is a mitigation step for CVE-2019-17558 on SOLR 6.1.  None of our solrconfig.xml contains the lib references to the velocity jar files as follows:
   
     <lib dir="${solr.install.dir:../../../..}/contrib/velocity/lib" regex=".*\.jar" />
     <lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-velocity-\d.*\.jar" />
     
   It doesn't appear that you can add these jars references using the config API.  Without these references, you are not able to flip the params.resource.loader.enabled to true using the config API.  If you are not able to flip the flag and none of your cores have these lib references then is the risk present?
   
   Thanks in advance!
