{"id":"CVE-2026-116796","published":"2026-10-28T18:17:14.460","lastModified":"2026-10-28T18:17:14.460","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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/highcharts/highcharts/commit/6cf359fb144aa51fdc105e2b9bbd013439b02c88","tags":[]},{"url":"https://github.com/highcharts/highcharts/releases/tag/v13.1.1","tags":[]},{"url":"https://github.com/highcharts/highcharts/security/advisories/GHSA-mw4f-gj5x-6xr4","tags":[]}],"exploitRefs":[{"url":"https://github.com/highcharts/highcharts/commit/6cf359fb144aa51fdc105e2b9bbd013439b02c88","tags":[]},{"url":"https://github.com/highcharts/highcharts/releases/tag/v13.1.1","tags":[]},{"url":"https://github.com/highcharts/highcharts/security/advisories/GHSA-mw4f-gj5x-6xr4","tags":[]}],"hasPoc":true,"ai":null}
