Summary

OpenPanel before 3.0.0 contains an improper escaping flaw in sankey.service.ts that lets authenticated project members break ClickHouse string literals by supplying backslashes in event names. An attacker 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. The weakness is classified as CWE-116.
