{"id":"GHSA-77r5-gw3j-2mpf","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","aliases":["CVE-2024-34350"],"modified":"2026-09-10T03:50:11.528318840Z","published":"2024-05-09T21:07:00Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2024-05-09T21:07:00Z","nvd_published_at":"2024-05-14T15:38:41Z","cwe_ids":["CWE-444"],"severity":"HIGH"},"references":[{"type":"WEB","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"}],"affected":[{"package":{"name":"next","ecosystem":"npm","purl":"pkg:npm/next"},"ranges":[{"type":"SEMVER","events":[{"introduced":"13.4.0"},{"fixed":"13.5.1"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/05/GHSA-77r5-gw3j-2mpf/GHSA-77r5-gw3j-2mpf.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:H/A:N"}]}
