AI-suggested
A fix is available in Apache ECharts version 6.1.0. Users and administrators should upgrade to version 6.1.0 or later to remediate this vulnerability. No official temporary or alternative mitigations are indicated in the provided data.
Description
Apache ECharts versions prior to 6.1.0 contain a cross-site scripting (XSS) vulnerability in the Lines series tooltip rendering logic. When using Lines series with tooltips and no custom tooltip.formatter, raw HTML content in series.data[i].name can be rendered without proper escaping, potentially allowing script execution. This vulnerability breaks the usual automatic HTML escaping convention in built-in tooltip formatters. The issue is fixed in version 6.1.0.
