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.","provenance":"source","from":"CVE.org"},"cvss":{"score":7.2,"severity":"HIGH","version":"4.0","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","provenance":"source","from":"CVE.org CNA"},"epss":{"score":0.00337,"percentile":0.27164,"provenance":"source"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"references":[{"url":"https://github.com/highcharts/highcharts/security/advisories/GHSA-mw4f-gj5x-6xr4","tags":["x_refsource_CONFIRM"]},{"url":"https://github.com/highcharts/highcharts/commit/6cf359fb144aa51fdc105e2b9bbd013439b02c88","tags":["x_refsource_MISC"]},{"url":"https://github.com/highcharts/highcharts/releases/tag/v13.1.1","tags":["x_refsource_MISC"]}],"priority":{"score":10.5,"factors":[{"name":"EPSS percentile","points":5.43},{"name":"CVSS severity","points":5.04}]},"vendorSlug":"highcharts","affectedVersions":[{"vendor":"highcharts","product":"highcharts","versions":[">= 10.3.2, < 11.4.9",">= 12.0.0, < 12.6.2",">= 13.0.0, < 13.1.1"]}],"affected":[{"ecosystem":"npm","package":"highcharts","vulnerableRanges":[">=10.3.2, <11.4.9",">=12.0.0, <12.6.2",">=13.0.0, <13.1.1"],"patched":["11.4.9","12.6.2","13.1.1"],"from":["GHSA-mw4f-gj5x-6xr4"],"provenance":"source"}],"euvd":{"id":"EUVD-2026-112279","exploited":false,"provenance":"source"},"lineage":{"familyId":"fam-highcharts-cve-2026-107588","parents":[{"from":"CVE-2026-107588","to":"CVE-2026-116796","relation":"related","confidence":"high","kind":"lineage","evidence":[{"kind":"osv-related","provenance":"source","id":"GHSA-mw4f-gj5x-6xr4","via":"related"}]}]}}
