CVE-2026-47846 — CRITICAL (9.8)

Vulnerability 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.
