Clickhouse: >> Clickhouse >> 19.14 Security Vulnerabilities
In all versions of ClickHouse before 19.14.3, an attacker having write access to ZooKeeper and who is able to run a custom server available from the network where ClickHouse runs, can create a custom-built malicious server that will act as a ClickHouse replica and register it in ZooKeeper. When another replica will fetch data part from the malicious replica, it can force clickhouse-server to write to arbitrary path on filesystem.
