SvelteKit has deserialization expansion in unvalidated `form` remote function leading to Denial of Service (experimental only)

Some relatively small inputs can cause very large files arrays in form handlers. If the SvelteKit application code doesn't check files.length or individual files' sizes and performs expensive processing with them, it can result in Denial of Service. Only users with experimental.remoteFunctions:...

GHSA-88QP-P4QG-RQM6 CPU exhaustion in SvelteKit remote form deserialization (experimental only)
