{"id":"BIT-cassandra-2026-47846","summary":"Default superuser cassandra:cassandra left active when CASSANDRA_USER is customized","details":"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. Any remote attacker who knows the default Cassandra credentials, can authenticate to the cluster as a full superuser regardless of the operator's configuration, bypassing the intent to replace the built-in account.","aliases":["CVE-2026-47846"],"modified":"2026-06-18T14:15:06.833167556Z","published":"2026-06-18T12:00:00Z","database_specific":{"severity":"Critical","cpes":["cpe:2.3:a:apache:cassandra:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://github.com/bitnami/containers/security/advisories/GHSA-8q3j-37vg-8fc2"}],"affected":[{"package":{"name":"cassandra","ecosystem":"Bitnami","purl":"pkg:bitnami/cassandra"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0"},{"fixed":"4.0.20-0"},{"introduced":"4.1.0"},{"fixed":"4.1.11-0"},{"introduced":"5.0.0"},{"fixed":"5.0.8-0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/cassandra/BIT-cassandra-2026-47846.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}],"schema_version":"1.7.5"}
