CVE-2026-27314: CWE-267 Privilege Defined With Unsafe Actions in Apache Software Foundation Apache Cassandra
Privilege escalation in Apache Cassandra 5.0 on an mTLS environment using MutualTlsAuthenticator allows a user with only CREATE permission to associate their own certificate identity with an arbitrary role, including a superuser role, and authenticate as that role via ADD IDENTITY. Users are recommended to upgrade to version 5.0.7+, which fixes this issue.
AI Analysis
Technical Summary
This vulnerability in Apache Cassandra 5.0 involves unsafe privilege definitions (CWE-267) in the MutualTlsAuthenticator component. Specifically, a user granted only CREATE permission can exploit the ADD IDENTITY functionality to link their certificate identity to arbitrary roles, including superuser roles, thereby escalating privileges improperly. The issue is resolved in version 5.0.7 and later.
Potential Impact
An attacker with limited CREATE permission can escalate privileges to superuser level by associating their certificate with arbitrary roles. This compromises the integrity of role-based access control in Apache Cassandra, potentially allowing unauthorized administrative actions.
Mitigation Recommendations
Users should upgrade Apache Cassandra to version 5.0.7 or later, where this vulnerability is fixed. No other mitigation guidance is provided. Patch status is confirmed by the vendor recommendation to upgrade.
