"The versions of the TanStack Start Node.js modules installed on the remote host are 1.143.12 or later, prior to their
respective patched versions. They are, therefore, affected by a cross-site scripting vulnerability:

  - The server-function transport passes request payload fields into internal middleware state instead of limiting
    them to public input fields, allowing an unauthenticated attacker to craft a URL to a server function that
    returns attacker-controlled HTML from the application's origin. If a visitor opens the URL, the injected script
    can access same-origin data and issue requests with the visitor's authority. (CVE-2026-102989)

The affected packages are @tanstack/start-server-core prior to 1.169.39, @tanstack/react-start prior to 1.168.60,
@tanstack/solid-start prior to 1.168.57, and @tanstack/vue-start prior to 1.168.56.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
