High (7.5) in apache cassandra. EPSS 2.0% chance of exploitation in the next 30 days. Fixed in org.apache.cassandra:cassandra-all 3.0.24, 3.11.10.

Apache Cassandra versions 2.1.0 to 2.1.22, 2.2.0 to 2.2.19, 3.0.0 to 3.0.23, and 3.11.0 to 3.11.9, when using 'dc' or 'rack' internode_encryption setting, allows both encrypted and unencrypted internode connections.
