Summary
Versions of `@sveltejs/kit` prior to 2.52.2 with remote functions enabled are vulnerable to CPU exhaustion. Malformed form data can cause the server to become unresponsive while processing a request, resulting in denial of service. Only applications using both `experimental.remoteFunctions` and `form` are vulnerable.
