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.","published_at":"2026-04-07T16:40:51.836000Z","last_modified_at":null,"cvss_v3_score":5.5,"cvss_v3_vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-532"],"nvd_references":["https://issues.apache.org/jira/browse/CASSANDRA-21180","https://lists.apache.org/thread/ft77zrk2mzt8qsch4g6jqjj4901d22k3"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:29:31.520288Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"L","value_label":"Local"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"N","value_label":"None"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"apache-software-foundation","vendor_name":"Apache Software Foundation","product_slug":"apache-cassandra","product_name":"Apache Cassandra","version_start":"4.0","version_start_inclusive":true,"version_end":"4.0.19","version_end_inclusive":true,"cpe23_uri":"cve5:apache-software-foundation:apache-cassandra:4.0:4.0.19"}],"exploit_refs":[],"news":[],"references":[{"url":"https://issues.apache.org/jira/browse/CASSANDRA-21180","source_type":"MISC","tags":[]},{"url":"https://lists.apache.org/thread/ft77zrk2mzt8qsch4g6jqjj4901d22k3","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2026-04-07T16:40:51.836000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:52:22.671512Z","label":"CVSS score revised","source":"cvelistv5"}]}
