Although tooltip is allowed to accept user-provided raw HTML via a custom tooltip.formatter, the built-in tooltip formatters conventionally perform HTML escaping automatically. This case breaks that convention and\u00a0may unexpectedly lead to script execution when tooltips are displayed.\\n\\n\\nUsers are recommended to upgrade to version 6.1.0 if using the Lines series in this way, which fixes the issue.”,”published”:”2026-05-25T07:38:07.398Z”,”modified”:”2026-05-26T16:17:41.575Z”,”type”:”cve”,”title”:”Apache ECharts: XSS in Lines series tooltip rendering”,”source”:”apache”,”references”:”https:\/\/github.com\/apache\/echarts\/pull\/21608\\nhttps:\/\/echarts.apache.org\/en\/option.html#series-lines\\nhttps:\/\/echarts.apache.org\/handbook\/en\/best-practices\/security\/#passing_raw_html_safely\\nhttps:\/\/lists.apache.org\/thread\/1g6xk7gd9vg1c6zyqqt2lnko10zomc3o”,”id”:”CVE-2026-45249″,”bulletinFamily”:””,”cwe”:[“CWE-79″],”cvelist”:null,”sourceData”:”Apache Software Foundation Apache ECharts 0″,”sourceHref”:””,”cvss”:{“score”:6.1,”severity”:”MEDIUM”,”vector”:”CVSS:3.1\/AV:N\/AC:L\/PR:N\/UI:R\/S:C\/C:L\/I:L\/A:N”,”version”:”3.1″},”cvss2″:{},”cvss3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””,”cvssV3″:{“version”:””,”vectorString”:””,”baseScore”:0,”baseSeverity”:””,”attackVector”:””,”attackComplexity”:””,”privilegesRequired”:””,”userInteraction”:””,”scope”:””,”confidentialityImpact”:””,”integrityImpact”:””,”availabilityImpact”:””}},”href”:””,”category_name”:”CVE”,”post_link”:””,”product”:”Apache ECharts”,”version”:”0″,”vendor”:”Apache Software Foundation”,”ai_description”:””,”ai_severity”:””,”ai_vendor”:””,”ai_product”:””,”ai_version”:””,”ai_score”:0}<\/p>\n","protected":false},"excerpt":{"rendered":"
