Prior to 21.0.0, Happy DOM loads iframe src URLs and link rel=\"stylesheet\" href URLs by default while parsing untrusted HTML on the server because disableIframePageLoading and disableCSSFileLoading default to false. An attacker who controls parsed HTML can therefore cause server-side requests to arbitrary internal or cloud endpoints without an application opt-in and may expose confidential responses or credentials returned by those endpoints. This issue is fixed in version 21.0.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N","score":8.6,"severity":null}],"references":["https://github.com/capricorn86/happy-dom/security/advisories/GHSA-c8p4-j97h-3vg8","https://github.com/capricorn86/happy-dom/pull/2502","https://github.com/capricorn86/happy-dom/commit/0a99c7525a1d0043e3182843ae33466ab7b19e74","https://github.com/capricorn86/happy-dom/releases/tag/v21.0.0"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-112467","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Oct 28, 2026, 8:23:10 PM","dateUpdated":"Oct 29, 2026, 5:23:32 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
