Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Apache Cassandra (org.apache.cassandra:cassandra-all) versions 4.0 before 4.0.20 are affected. The cqlsh tool saves command history without redacting passwords, so anyone with local access to a user's ~/.cassandra/cqlsh_history file can read passwords from earlier commands. Upgrade to version 4.0.20, which fixes the issue.
