How to fix?

Upgrade org.apache.solr:solr-core to version 6.6.6, 7.7.0 or higher.

Overview

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

Affected versions of this package are vulnerable to Authentication Bypass. In Apache Solr, the cluster can be partitioned into multiple collections and only a subset of nodes actually host any given collection. However, if a node receives a request for a collection it does not host, it proxies the request to a relevant node and serves the request. Solr bypasses all authorization settings for such requests.

This affects all Solr that use the default authorization mechanism of Solr (RuleBasedAuthorizationPlugin).
