CVE-2026-47846 PUBLISHED

Assigner: vmware
Reserved: 20.05.2026 Published: 18.06.2026 Updated: 18.06.2026

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.

Problem Types

CWE-798: Use of Hard-coded Credentials CWE

Impacts

Remote attackers with network access to the Cassandra CQL port can authenticate using the default cassandra:cassandra credentials to obtain full superuser privileges, allowing complete read and write access to all keyspaces and tables, including dropping keyspaces and altering cluster topology (High Confidentiality, Integrity, and Availability impact).
