CVE-2026-111670
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.
Does this matter?
Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.
Description
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.
