  - Next.js is a React framework for building full-stack web applications. 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. (CVE-2025-32421)

Note that Nessus relies on the presence of the package as reported by the vendor.");
