ClickHouse is an open-source column-oriented database management system. A bug exists in the cloud ClickHouse offering prior to version 24.0.2.54535 and in github.com/clickhouse/clickhouse version 23.1. Query caching bypasses the role based access controls and the policies being enforced on roles. In affected versions, the query cache only respects separate users, however this is not documented and not expected behavior. People relying on ClickHouse roles can have their access control lists bypassed if they are using query caching. • https://github.com/ClickHouse/ClickHouse/blob/bd17ee769e337906c4b1f404861e042ad72fcbfc/src/Interpreters/executeQuery.cpp#L1013-L1015 https://github.com/ClickHouse/ClickHouse/pull/58611 https://github.com/ClickHouse/ClickHouse/security/advisories/GHSA-45h5-f7g3-gr8r • CWE-863: Incorrect Authorization •
