{"id":"CVE-2026-118255","summary":"Highcharts Grid: javascript: URL in credits.href runs script on click","details":"Highcharts JS is a JavaScript charting library based on SVG. From 2.0.0 until 3.2.0, Highcharts Grid applies credits.href to the credits link without validating the URL scheme. An attacker who controls Grid configuration can provide a javascript URL, and activating the credits link runs script in the origin of the hosting page with access to that application's data and session state.This issue is fixed in Grid Pro 3.2.0.","aliases":["GHSA-6hgp-fmhr-mrg4"],"modified":"2026-10-29T02:48:31.631500505Z","published":"2026-10-28T18:17:14.543Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/118xxx/CVE-2026-118255.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/118xxx/CVE-2026-118255.json"},{"type":"FIX","url":"https://github.com/highcharts/highcharts/commit/45b74403acafbe9f621c4a343506721d9129e991"},{"type":"FIX","url":"https://github.com/highcharts/highcharts/pull/25351"},{"type":"WEB","url":"https://github.com/highcharts/highcharts/releases/tag/grid-v3.2.0"},{"type":"ADVISORY","url":"https://github.com/highcharts/highcharts/security/advisories/GHSA-6hgp-fmhr-mrg4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-118255"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/highcharts/highcharts","events":[{"introduced":"0"},{"fixed":"283f2c015f0e2830d7eb53714ce894efc227b1c7"},{"introduced":"a7cf00c9b884aa7ebaad57d6dca4032bbc0409f3"},{"fixed":"1aaa4368e36f90a6909ed1adb6e3675c800f9374"},{"introduced":"1aaa4368e36f90a6909ed1adb6e3675c800f9374"},{"fixed":"a7cf00c9b884aa7ebaad57d6dca4032bbc0409f3"},{"fixed":"45b74403acafbe9f621c4a343506721d9129e991"}],"database_specific":{"extracted_events":[{"range":[{"introduced":"0"},{"fixed":"13.0.0-beta.2"}],"source":"AFFECTED_FIELD","strategy":"StringRangeExpression"},{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"3.2.0"},{"fixed":"4.0.0"}]},{"source":"AFFECTED_FIELD","strategy":"StringRangeExpression","range":[{"introduced":"2.0.0"},{"fixed":"3.2.0"}]},{"source":"REFERENCES_COMMIT","range":[{"fixed":"45b74403acafbe9f621c4a343506721d9129e991"}]},{"original_tag":"grid-v3.2.0","range":[{"fixed":"a7cf00c9b884aa7ebaad57d6dca4032bbc0409f3"}],"source":"REFERENCES_TAG"}]}}],"versions":["v13.0.0","v13.0.2","v13.0.1","dashboards-v4.2.1","grid-v3.1.0","v13.0.0-beta.1","dashboards-v4.2.0","grid-v3.0.0","v12.6.0","grid-v2.3.1","grid-v2.3.0","dashboards-v4.1.0","grid-v2.2.0","v12.5.0","grid-v2.1.0","grid-v2.0.1","dashboards-v4.0.0","grid-v2.0.0","dashboards-v3.6.0","grid-v1.4.0","v12.4.0","grid-v1.3.0","dashboards-v3.5.0","grid-v1.2.0","dashboards-v3.4.0","v12.3.0","grid-v1.1.0","dashboards-v3.3.0","v12.2.0","grid-v1.0.1","dashboards-v3.2.0","grid-v1.0.0","v12.1.2","v12.1.1","v12.1.0","dashboards-v3.1.0","v12.0.2","v12.0.1","v12.0.0","v11.4.8","dashboards-v2.3.0","v11.4.7","v11.4.6","v11.4.5","v11.4.4","dashboards-v2.2.0","v11.4.3","v11.4.2","dashboards-v2.1.0","dashboards-v2.0.0","v11.4.0","dashboards-v1.3.1","dashboards-v1.3.0","dashboards-v1.2.1","v11.3.0","dashboards-v1.2.0","dashboards-v1.1.3","dashboards-v1.1.2","v11.2.0","dashboards-v1.1.1","dashboards-v1.1.0","dashboards-v1.0.1","dashboards-v1.0.0","v11.1.0","v11.0.1","v11.0.0","v10.3.2","v10.3.1","v10.3.0","v10.2.0","v10.1.0","v10.0.0","v9.3.1","v9.3.0","v9.2.2","v9.2.1","v9.2.0","v9.1.2","v9.1.1","v9.1.0","v9.0.1","v9.0.0","v8.2.2","v8.1.2","v8.1.1","v8.1.0","v8.0.4","v8.0.3","v8.0.2","v8.0.1","v8.0.0","v7.2.0","v7.1.2","v7.1.0","v7.0.2","v7.0.1","hc6/master-tag","v6.2.0","v5.0.0","v4.1.3","highstock-v2.1.3","highmaps-v2.1.3","v4.1.0","highstock-v2.1.0","highmaps-v1.1.0","highmaps-v1.0.2","v4.0.1","highstock-v2.0.1","v3.0.8","highstock-v1.3.8","v3.0.5","highstock-v1.3.5","v3.0.4","highstock-v1.3.4","v3.0.3","highstock-v1.3.3","v3.0.2","highstock-v1.3.2","v3.0.1","highstock-v1.3.1","v3.0.0","highstock-v1.3.0","v2.3.5","highstock-v1.2.5","highstock-v1.2.4","v2.3.3","highstock-v1.2.3","v2.3.2","highstock-v1.2.2","v2.3.0","highstock-v1.2.0","highstock-v1.1.6","v2.2.5","v2.2.4","v2.2.2","highstock-v1.1.5","v2.2.1","highstock-v1.1.4","highstock-v1.1.3","highstock-v1.1.2","highstock-v1.1.1","highstock-v1.1.0","highstock-v1.0.1","v2.1.5","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.5","v2.0.4","v2.0.3","v2.0.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-118255.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:A/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N"}]}
