CVE-2026-116815 Details
Description
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.
A vulnerability exists in OpenPanel versions prior to 3.0.0, specifically within the 'sankey.service.ts' file. This issue involves improper escaping of string literals for ClickHouse, allowing authenticated project members to disrupt the parsing of event names by introducing backslashes. Attackers with read access can exploit this by sending crafted event names to the 'chart.sankey' procedure, leading to ClickHouse parse errors that disrupt the project's Sankey chart functionality.
Replace the manual string escaping in 'sankey.service.ts' with the 'sqlstring.escape' method, which properly handles backslashes. This change should be applied to all affected lines in the file.
