{"id":"CVE-2024-34350","aliases":["GHSA-77r5-gw3j-2mpf"],"url":"https://o3.security/vulnerability/CVE-2024-34350","summary":"Next.js Vulnerable to HTTP Request Smuggling","details":"### Impact\nInconsistent interpretation of a crafted HTTP request meant that requests are treated as both a single request, and two separate requests by Next.js, leading to desynchronized responses. This led to a response queue poisoning vulnerability in the affected Next.js versions.\n\nFor a request to be exploitable, the affected route also had to be making use of the [rewrites](https://nextjs.org/docs/app/api-reference/next-config-js/rewrites) feature in Next.js.\n\n### Patches\nThe vulnerability is resolved in Next.js `13.5.1` and newer. This includes Next.js `14.x`.\n\n### Workarounds\nThere are no official workarounds for this vulnerability. We recommend that you upgrade to a safe version.\n\n### References\nhttps://portswigger.net/web-security/request-smuggling/advanced/response-queue-poisoning","published":"2024-05-09T16:07:44.499Z","modified":"2026-08-12T03:51:20.487421716Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"npm","name":"next","fixedVersion":"13.5.1"}],"fix":{"url":"https://github.com/vercel/next.js/commit/44eba020c615f0d9efe431f84ada67b81576f3f5","label":"vercel/next.js@44eba02"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/34xxx/CVE-2024-34350.json"},{"type":"ADVISORY","url":"https://github.com/vercel/next.js/security/advisories/GHSA-77r5-gw3j-2mpf"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-34350"},{"type":"WEB","url":"https://github.com/vercel/next.js/commit/44eba020c615f0d9efe431f84ada67b81576f3f5"},{"type":"PACKAGE","url":"https://github.com/vercel/next.js"},{"type":"WEB","url":"https://github.com/vercel/next.js/compare/v13.5.0...v13.5.1"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:20.487421716Z"}}
