CVE-2026-47846

Retained Default Superuser Enables Privilege Escalation

Published Jun 18, 2026 CVSS 3.1 · 9.8 Critical EPSS < 1% KEV · Not listed
Description
Bitnami Cassandra container images are affected by a retained default superuser vulnerability. When a custom administrator account is configured via the CASSANDRA_USER environment variable, the container initialization script creates the new superuser account but fails to drop the built-in cassandra account in certain scenarios. This leaves the default cassandra:cassandra superuser active as an unintended access path.

Affected versions — Container image: 4.0.x prior to 4.0.20-photon-5-r7; 4.1.x prior to 4.1.11-photon-5-r7; 5.0.x prior to 5.0.8-photon-5-r4 / 5.0.8-debian-12-r3.
