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 may 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://echarts.apache.org/en/option.html#series-lines","https://echarts.apache.org/handbook/en/best-practices/security/#passing_raw_html_safely","https://github.com/apache/echarts/pull/21608","https://lists.apache.org/thread/1g6xk7gd9vg1c6zyqqt2lnko10zomc3o","http://www.openwall.com/lists/oss-security/2026/05/23/4"],"products":["apache:echarts"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-45249","score":0.00749,"percentile":0.54923,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-fgmj-fm8m-jvvx","url":"https://osv.dev/vulnerability/GHSA-fgmj-fm8m-jvvx","summary":"Apache ECharts has a cross-site scripting (XSS) vulnerability","modified":"2026-09-10T03:50:46.703392703Z","packages":[{"ecosystem":"npm","name":"echarts","purl":"pkg:npm/echarts","ranges":["<6.1.0"],"fixed":["6.1.0"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
