{"cve":"CVE-2026-116796","nvd":{"published":"2026-10-28T18:17:14.460","modified":"2026-10-28T18:17:14.460","status":"Received","description":"Highcharts JS is a JavaScript charting library based on SVG. From 10.3.2 until 11.4.9, 12.6.2, and 13.1.1, Highcharts accepts an SVG anchor xlink:href attribute without applying the allowed-scheme check used for href and src. An attacker who controls a chart text option can preserve a javascript URL in serialized chart output. When exported or server-rendered SVG is parsed again and a user activates the link, script runs in the origin of that document. This issue is fixed in 11.4.9, 12.6.2 and 13.1.1.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N","score":7.2},"cvss_v3":null,"cwes":["CWE-79"],"references":["https://github.com/highcharts/highcharts/commit/6cf359fb144aa51fdc105e2b9bbd013439b02c88","https://github.com/highcharts/highcharts/releases/tag/v13.1.1","https://github.com/highcharts/highcharts/security/advisories/GHSA-mw4f-gj5x-6xr4"],"products":[],"source":"nvd","synced_at":"2026-10-28T18:33:43.673322083+00:00"},"epss":null,"kev":null,"osv":[],"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).
