+  "summary": "## Summary\nWhen Next.js rewrites proxy traffic to an external backend, a crafted `DELETE`/`OPTIONS` request using `Transfer-Encoding: chunked` could trigger request boundary disagreement between the proxy and backend. This could allow request smuggling through rewritten routes.\n\n## Impact\nAn attacker could smuggle a second request to unintended backend routes (for example, internal/admin endpoints), bypassing assumptions that only the configured rewrite destination/path is reachable. This does not impact applications hosted on providers that handle rewrites at the CDN level, such as Vercel. \n\n## Patches\nThe vulnerability originated in an upstream library vendored by Next.js. It is fixed by updating that dependency\u2019s behavior so `content-length: 0` is added only when both `content-length` and `transfer-encoding` are absent, and `transfer-encoding` is no longer removed in that code path.\n\n## Workarounds\nIf upgrade is not immediately possible:\n- Block chunked `DELETE`/`OPTIONS` requests on rewritten routes at your edge/proxy.\n- Enforce authentication/authorization on backend routes per our [security guidance](https://nextjs.org/docs/app/guides/data-security).",
