How to fix?

Upgrade org.apache.solr:solr-core to version 7.1.0 or higher.


org.apache.solr:solr-core is an open source enterprise search platform built on Apache Lucene

Affected versions of this package are vulnerable to Remote Code Execution (RCE). One can issue a HTTP request parameter stream.body which Solr will interpret as body content on the request, i.e. act as a POST request. This is useful for development and testing but can pose a security risk in production since users/clients with permission to GET on various endpoints can also post by using stream.body. The classic example is &stream.body=<delete><query>:</query></delete>. Furthermore, this feature cannot be turned off by configuration as it is not controlled by enableRemoteStreaming.
