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.","state":0,"publishedAt":"2026-10-28T17:23:02.604+00:00","modifiedAt":"2026-10-28T17:23:02.604+00:00","affected":[{"ecosystem":"Vendor product","name":"highcharts","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"highcharts\",\n                    \"product\": \"highcharts\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 10.3.2, < 11.4.9\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 12.0.0, < 12.6.2\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 13.0.0, < 13.1.1\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 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","score":7.2,"severity":"HIGH"}],"references":["https://github.com/highcharts/highcharts/security/advisories/GHSA-mw4f-gj5x-6xr4","https://github.com/highcharts/highcharts/commit/6cf359fb144aa51fdc105e2b9bbd013439b02c88","https://github.com/highcharts/highcharts/releases/tag/v13.1.1"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-116796","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-116796","identifiers":["CVE-2026-116796"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
