{"schema_version": "1.6.1", "id": "CVE-2026-27315", "summary": "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.", "affected": [{"ranges": [{"type": "SEMVER", "events": [{"introduced": "4.0"}, {"last_affected": "4.0"}]}]}], "references": [{"type": "REPORT", "url": "https://issues.apache.org/jira/browse/CASSANDRA-21180"}, {"type": "WEB", "url": "https://lists.apache.org/thread/ft77zrk2mzt8qsch4g6jqjj4901d22k3"}]}
