Upgrade org.apache.cassandra:cassandra-all to version 5.0.7 or higher.
Overview
org.apache.cassandra:cassandra-all is a maven plugin for the Apache Cassandra Project. Which, develops a highly scalable second-generation distributed database, bringing together Dynamo's fully distributed design and Bigtable's ColumnFamily-based data model.
Affected versions of this package are vulnerable to Privilege Defined With Unsafe Actions through the AddIdentityStatement and DropIdentityStatement authorization paths in src/java/org/apache/cassandra/cql3/statements/. An attacker can bind their own certificate identity to an arbitrary role, including a superuser role, or remove identity bindings from privileged roles by sending ADD IDENTITY or DROP IDENTITY requests after obtaining the relevant CREATE or DROP role permission. This lets a regular mTLS user authenticate as a higher-privileged role and gain that role’s access, exposing administrative capabilities and control over the cluster.
