Retained Default Superuser in Bitnami Cassandra Container Images

IdentifiersCVE-2026-47846CWE-1392

CVE-2026-47846 is a critical vulnerability in Bitnami Cassandra container images caused by improper removal of a default privileged account during container initialization. When a custom administrator account is configured via the CASSANDRA_USER environment variable, the initialization logic creates the new superuser account but, in certain scenarios, fails to delete or disable the built-in cassandra account. As a result, the default cassandra:cassandra credentials may remain valid and usable as a superuser access path. The issue affects Bitnami Cassandra container images 4.0.x prior to 4.0.20-photon-5-r7, 4.1.x prior to 4.1.11-photon-5-r7, and 5.0.x prior to 5.0.8-photon-5-r4 or 5.0.8-debian-12-r3.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows an attacker to authenticate remotely to the affected Cassandra instance using the retained default superuser account. Because the account has superuser privileges, compromise can result in full administrative control over the database, including unauthorized access to data, modification or deletion of records and configuration, and actions that can disrupt service availability. The provided CVSS context indicates high confidentiality, integrity, and availability impact.

Mitigation

If you can’t patch tonight, do this now.

If immediate patching is not possible, manually inspect affected Cassandra deployments to determine whether the default cassandra superuser account is still present and active, and remove or disable it. Restrict network exposure to Cassandra management and client interfaces to trusted hosts only, and ensure custom administrator credentials are configured and validated. Monitor authentication activity for use of the cassandra account and treat any successful login with default credentials as a potential compromise indicator.

Remediation

Patch, then assume compromise.

Update affected Bitnami Cassandra container images to fixed versions: 4.0.20-photon-5-r7 or later, 4.1.11-photon-5-r7 or later, and 5.0.8-photon-5-r4 / 5.0.8-debian-12-r3 or later, as applicable. After upgrading, verify that the built-in cassandra account has been removed or disabled where a custom administrator account is intended to replace it. Review existing deployments for exposure and rotate credentials if there is any possibility the default account remained accessible.
