From 13.4.0 to before 15.5.16 and 16.2.5, App Router applications that rely on CSP nonces can be vulnerable to stored cross-site scripting when deployed behind shared caches. In affected versions, malformed nonce values derived from request headers could be reflected into rendered HTML in an unsafe way, allowing an attacker to poison cached responses and cause script execution for later visitors. This vulnerability is fixed in 15.5.16 and 16.2.5.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N","score":4.7,"severity":null}],"references":["https://github.com/vercel/next.js/security/advisories/GHSA-ffhc-5mcf-pf4q"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-30083","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"May 13, 2026, 5:07:15 PM","dateUpdated":"May 18, 2026, 2:13:33 PM"},"relatedAdvisories":[{"id":"WID-SEC-W-2026-1401","title":"Vercel Next.js: Mehrere Schwachstellen","vulnerabilityIds":["CVE-2026-23870","CVE-2026-44572","CVE-2026-44573","CVE-2026-44574","CVE-2026-44575","CVE-2026-44576","CVE-2026-44577","CVE-2026-44578","CVE-2026-44579","CVE-2026-44580","CVE-2026-44581","CVE-2026-44582"]}],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
