From 13.0.0 until 13.1.0, Highcharts builds series data columns by using point option keys directly as column IDs. Own enumerable __proto__ and constructor keys from parsed point objects can therefore direct integer-indexed writes to Object.prototype or the Object constructor. The inherited values affect reads and for-in enumeration across the page and can disrupt rendering or alter consuming application behavior without user interaction beyond rendering the chart. This issue is fixed in 13.1.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:H/VA:H/SC:L/SI:L/SA:L","score":7.2,"severity":null}],"references":["https://github.com/highcharts/highcharts/security/advisories/GHSA-gfvx-2c2g-38wq","https://github.com/highcharts/highcharts/pull/25321","https://github.com/highcharts/highcharts/commit/d3357705c8f348904441327e32f50ab528c3a205","https://github.com/highcharts/highcharts/releases/tag/v13.1.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112363","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 28, 2026, 5:57:18 PM","dateUpdated":"Oct 29, 2026, 8:55:21 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
