Vulnerability from github – Published: 2026-04-07 18:31 – Updated: 2026-04-08 19:22

Summary

Apache Cassandra is vulnerable to privilege escalation in an mTLS environment using MutualTlsAuthenticator

Details

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.

Severity ?

8.8 (High)
