Node.js Module TanStack Start 1.143.12 < 1.168.56 / 1.168.57 / 1.168.60 / 1.169.39 XSS (CVE-2026-102989)

critical Nessus Plugin ID 371390

Synopsis

Modules in the Node.js JavaScript run-time environment are affected by a cross-site scripting vulnerability.

Description

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.

Solution

Upgrade @tanstack/start-server-core to version 1.169.39, @tanstack/react-start to version 1.168.60, @tanstack/solid-start to version 1.168.57, or @tanstack/vue-start to version 1.168.56 or later.
