{"id":"CVE-2025-57822","state":"PUBLISHED","title":"Next.js Improper Middleware Redirect Handling Leads to SSRF","description":"Next.js is a React framework for building full-stack web applications. Prior to versions 14.2.32 and 15.4.7, when next() was used without explicitly passing the request object, it could lead to SSRF in self-hosted applications that incorrectly forwarded user-supplied headers. This vulnerability has been fixed in Next.js versions 14.2.32 and 15.4.7. All users implementing custom middleware logic in self-hosted environments are strongly encouraged to upgrade and verify correct usage of the next() function.","publishedAt":"2025-08-29T21:33:15.304Z","updatedAt":"2025-09-02T17:26:25.016Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:L/A:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["vercel next.js"],"affected":[{"vendor":"vercel","product":"next.js","versions":[{"version":"< 14.2.32","status":"affected"},{"version":"< 15.4.7","status":"affected"}]}],"references":["https://github.com/vercel/next.js/security/advisories/GHSA-4342-x723-ch2f","https://github.com/vercel/next.js/commit/9c9aaed5bb9338ef31b0517ccf0ab4414f2093d8","https://vercel.com/changelog/cve-2025-57822"],"weaknesses":["CWE-918"],"ingestedAt":"2026-10-29T20:09:39.787Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/57xxx/CVE-2025-57822.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-57822","state":"PUBLISHED","datePublished":"2025-08-29T21:33:15.304Z","dateUpdated":"2025-09-02T17:26:25.016Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-08-20T14:30:35.011Z"},"containers":{"cna":{"title":"Next.js Improper Middleware Redirect Handling Leads to SSRF","descriptions":[{"lang":"en","value":"Next.js is a React framework for building full-stack web applications.
