ClickVisual through 1.1.2 contains a missing authorization vulnerability in the /api/v2/reports handlers that allows authenticated low-privileged users to access ClickHouse instances they were not granted. Attackers can iterate the instance-id parameter in ReportSourceDatabases, ReportSourceTables, ReportTableColumns and WhereCheckRun to enumerate schemas and infer row counts of restricted tables.
