From 15.0.0 until 15.5.27 and 16.3.8, applications with a root-level catch-all page and statically generated or Incremental Static Regeneration routes can use a shared response cache key that is insufficiently scoped to the source route. A single unauthenticated crafted request can poison that cache, causing cross-user content substitution or persistent denial of service until the poisoned entry is revalidated or replaced. This issue is fixed in versions 15.5.27 and 16.3.8.","state":0,"publishedAt":"2026-10-02T15:26:48.417+00:00","modifiedAt":"2026-10-05T20:07:39.105+00:00","affected":[{"ecosystem":"Vendor product","name":"next.js","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"vercel\",\n                    \"product\": \"next.js\",\n                    \"versions\": [\n                        {\n                            \"version\": \">= 15.0.0, < 15.5.27\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \">= 16.0.0, < 16.3.8\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:N/AC:H/AT:P/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":6.3,"severity":"MEDIUM"}],"references":["https://github.com/vercel/next.js/security/advisories/GHSA-mcj8-r9mp-w47p","https://github.com/vercel/next.js/commit/52c94abdd2ea5f416f5e8353ea8a2edd3fe311b8","https://github.com/vercel/next.js/commit/719e4c67d6e92df60246f95e1d96e2dd60789a52","https://github.com/vercel/next.js/releases/tag/v15.5.27","https://github.com/vercel/next.js/releases/tag/v16.3.8"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-94484","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-94484","identifiers":["CVE-2026-94484"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
