Apache Cassandra versions 4.0 before 4.0.20, 4.1 before 4.1.11, and 5.0 before 5.0.7 (Maven package org.apache.cassandra:cassandra-all) are affected. An authenticated user can raise query latencies by repeatedly changing their password over CQL, causing a denial of service. Upgrade to 4.0.20, 4.1.11, 5.0.7, or a later version.
