Summary

CPU exhaustion in SvelteKit remote form deserialization (experimental only)

Details

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.
