CVE-2026-47846: Bitnami Bitnami/cassandra

Critical severity, CVSS 9.8. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products

• Bitnami Bitnami/cassandra: from 4.0.0, before 4.0.20-photon-5-r7 (fixed in 4.0.20-photon-5-r7); from 4.1.0, before 4.1.11-photon-5-r7 (fixed in 4.1.11-photon-5-r7); from 5.0.0, before 5.0.8-photon-5-r4 (fixed in 5.0.8-photon-5-r4)
