| Doc Text: |
A flaw was found in the Next.js package. 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.
