Memory exhaustion in SvelteKit remote form deserialization (experimental only)
Publisher and source text is retained separately from QFinch interpretation.
QFinch assessment
Versions of `@sveltejs/kit` prior to 2.52.2 with remote functions enabled can be vulnerable to memory exhaustion. Malformed form data can cause the server process to crash due to excessive memory allocation, resulting in denial of service.
