Impact

The @tanstack/react-query-next-experimental NPM package is vulnerable to a cross-site scripting vulnerability. To exploit this, an attacker would need to either inject malicious input or arrange to have malicious input be returned from an endpoint.

This vulnerability arises from improper handling of untrusted input when @tanstack/react-query-next-experimental performs server-side rendering of HTML pages. To fix this vulnerability, we implemented appropriate escaping to prevent javascript injection into rendered pages.
