Stratio · Cassandra-Lucene-Index · CVE-2025-26511
Name of the Vulnerable Software and Affected Versions:
Instaclustr fork of Stratio's Cassandra-Lucene-Index plugin versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0
Instaclustr fork of Stratio's Cassandra-Lucene-Index plugin versions 4.1.0-1.0.0 through 4.1.8-1.0.0
Description:
The vulnerability allows authenticated Cassandra users to remotely bypass Role-Based Access Control (RBAC) and escalate their privileges. This can be exploited when the required conditions are met, including the use of Cassandra 4.x, a vulnerable version of the Cassandra-Lucene-Index plugin, data added to tables, a Lucene index created, and Cassandra flush has run.
Recommendations:
For versions 4.0-rc1-1.0.0 through 4.0.16-1.0.0, upgrade to a fixed version of the Cassandra-Lucene-Index plugin.
For versions 4.1.0-1.0.0 through 4.1.8-1.0.0, upgrade to a fixed version of the Cassandra-Lucene-Index plugin.
As a temporary workaround, consider dropping all Lucene indexes and stopping the use of the plugin to prevent exploitation.
Review users in Cassandra to validate all superuser privileges.
