{"id":"BIT-cassandra-2026-27315","summary":"Apache Cassandra: cqlsh history sensitive information leak","details":"Sensitive Information Leak in cqlsh in Apache Cassandra 4.0 allows access to sensitive information, like passwords, from previously executed cqlsh command via  ~/.cassandra/cqlsh_history local file access.\n\nUsers are recommended to upgrade to version 4.0.20, which fixes this issue.\n\n--\nDescription: Cassandra's command-line tool, cqlsh, provides a command history feature that allows users to recall previously executed commands using the up/down arrow keys. These history records are saved in the ~/.cassandra/cqlsh_history file in the user's home directory.\n\nHowever, cqlsh does not redact sensitive information when saving command history. This means that if a user executes operations involving passwords (such as logging in or creating users) within cqlsh, these passwords are permanently stored in cleartext in the history file on the disk.","aliases":["CVE-2026-27315","GHSA-fh34-c629-p8xj"],"modified":"2026-09-08T08:45:58.063644644Z","published":"2026-04-09T08:36:45.141Z","database_specific":{"cpes":["cpe:2.3:a:apache:cassandra:*:*:*:*:*:*:*:*"],"severity":"Medium"},"references":[{"type":"ADVISORY","url":"http://www.openwall.com/lists/oss-security/2026/04/07/8"},{"type":"ADVISORY","url":"https://issues.apache.org/jira/browse/CASSANDRA-21180"},{"type":"ADVISORY","url":"https://lists.apache.org/thread/ft77zrk2mzt8qsch4g6jqjj4901d22k3"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-27315"}],"affected":[{"package":{"name":"cassandra","ecosystem":"Bitnami","purl":"pkg:bitnami/cassandra"},"ranges":[{"type":"SEMVER","events":[{"introduced":"4.0.0"},{"fixed":"4.0.20"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/cassandra/BIT-cassandra-2026-27315.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"}]}],"schema_version":"1.9.0"}
