Versions prior to 14.2.24 and 15.1.6 have a race-condition vulnerability. This issue only affects the Pages Router under certain misconfigurations, causing normal endpoints to serve `pageProps` data instead of standard HTML. This issue was patched in versions 15.1.6 and 14.2.24 by stripping the `x-now-route-matches` header from incoming requests. Applications hosted on Vercel's platform are not affected by this issue, as the platform does not cache responses based solely on `200 OK` status without explicit `cache-control` headers. Those who self-host Next.js deployments and are unable to upgrade immediately can mitigate this vulnerability by stripping the `x-now-route-matches` header from all incoming requests at the content development network and setting `cache-control: no-store` for all responses under risk. The maintainers of Next.js strongly recommend only caching responses with explicit cache-control headers.\n\ud83d\udccf Published: 2025-05-14T22:56:45.624Z\n\ud83d\udccf Modified: 2025-05-14T22:56:45.624Z\n\ud83d\udd17 References:\n1. https://github.com/vercel/next.js/security/advisories/GHSA-qpjv-v59x-3qc4\n2. https://vercel.com/changelog/cve-2025-32421", "creation_timestamp": "2025-05-14T23:33:28.000000Z"}
