CVE-2026-116815

OpenPanel before 3.0.0 contains an improper escaping vulnerability in sankey.service.ts that allows authenticated project members to break ClickHouse string literals by supplying backslashes in event names. Attackers with read access can submit crafted events[].name values to the chart.sankey procedure, causing ClickHouse parse errors that disable the project's Sankey chart endpoint.
