To mitigate CVE-2025-29927, Next.js validated the x-middleware-subrequest-id which persisted across multiple incoming requests. However, this subrequest ID is sent to all requests, even if the destination is not the same host as the Next.js application. Initiating a fetch request to a third-party within Middleware will send the x-middleware-subrequest-id to that third party. This vulnerability is fixed in 12.3.6, 13.5.10, 14.2.26, and 15.2.4.\n\ud83d\udccf Published: 2025-04-02T21:23:14.660Z\n\ud83d\udccf Modified: 2025-04-02T21:23:14.660Z\n\ud83d\udd17 References:\n1. https://github.com/vercel/next.js/security/advisories/GHSA-223j-4rm8-mrmf\n2. https://vercel.com/changelog/cve-2025-30218-5DREmEH765PoeAsrNNQj3O", "creation_timestamp": "2025-04-02T21:34:07.000000Z"}]}
