{"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":"Next.js is a React framework that can provide building blocks to create web applications. Prior to 13.5.1, an inconsistent 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. For 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. The vulnerability is resolved in Next.js `13.5.1` and newer.","published":"2024-05-09T16:07:44.499Z","modified":"2026-07-15T01:49:21.312057651Z","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":null,"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"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:21.312057651Z"}}
