Chartbrew is an open-source web application that can connect directly to databases and APIs and use the data to create charts. Prior to 5.2.3, Chartbrew's ClickHouse protocol in server/sources/plugins/clickhouse/clickhouse.protocol.js calls applySqlVariables() from server/sources/shared/sql/sql.variables.js without enabling the escapeBackslash option. For a ClickHouse-backed chart with variable binding, an attacker can supply a backslash before a quote so quote doubling does not keep the value within its intended SQL string literal. Public dashboards can expose this path without authentication, and successful exploitation can execute arbitrary ClickHouse SQL to disclose data or, when the database configuration permits, access files or internal network resources. This issue is fixed in version 5.2.3.
CVE-2026-65980
This high-severity CVE scores 7.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.7%, top 51% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).
- High severity, but no confirmed exploitation yet
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
