Affected: Maven: com.instaclustr:cassandra-lucene-index-plugin

**Summary / Details** Systems running the Instaclustr fork of Stratio's Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0 and 4.1.0-1.0.0 through 4.1.8-1.0.0, installed into Apache Cassandra version 4.x, are susceptible to a vulnerability which when successfully exploited could allow authenticated Cassandra users to remotely bypass RBAC to access data and and escalate their privileges.

**Affected Versions** - Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0 - versions 4.1.0-1.0.0 through 4.1.8-1.0.0 when installed into Apache Cassandra version 4.x.

**Required Configuration for Exploit** These are the conditions required to enable exploit: 1. Cassandra 4.x 2. Vulnerable version of the Cassandra-Lucene-Index plugin configured for use 3. Data added to tables 4. Lucene index created 5. Cassandra flush has run

**Mitigation/Prevention** Mitigation requires dropping all Lucene indexes and stopping use of the plugin. Exploit will be possible any time the required conditions are met.

**Solution** Upgrade to a fixed version of the Cassandra-Lucene-Index plugin. Review users in Cassandra to validate all superuser privileges.
