Description

Incorrect Authorization vulnerability in Apache Cassandra allowing users to access a datacenter or IP/CIDR groups they should not be able to when using CassandraNetworkAuthorizer or CassandraCIDRAuthorizer.

Users with restricted data center access can update their own permissions via data control language (DCL) statements on affected versions.

This issue affects Apache Cassandra: from 4.0.0 through 4.0.15 and from 4.1.0 through 4.1.7 for CassandraNetworkAuthorizer, and from 5.0.0 through 5.0.2 for both CassandraNetworkAuthorizer and CassandraCIDRAuthorizer.

Operators using CassandraNetworkAuthorizer or CassandraCIDRAuthorizer on affected versions should review data access rules for potential breaches. Users are recommended to upgrade to versions 4.0.16, 4.1.8, 5.0.3, which fixes the issue.

Detection & mitigation playbook

Open-source dependency
  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.apache.cassandra:cassandra-all, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update org.apache.cassandra:cassandra-all to 4.0.16 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3cjf-fwcq-xh22 is resolved across your whole dependency graph.

  3. Workarounds

    Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.
