Technical details
The ClickHouse protocol handler in Chartbrew calls applySqlVariables() without enabling the escapeBackslash option, allowing SQL injection through quote-doubling bypass via backslash prefix. An attacker can supply a backslash before a quote character to escape the quote protection mechanism and inject arbitrary SQL. Public dashboards without authentication requirements provide the attack vector; successful exploitation allows arbitrary ClickHouse SQL execution with potential for data disclosure or file system access depending on database permissions.
