Prerendered pages and SvelteKit 1 apps are not affected. <!-- ### Details _Give all details on the vulnerability. Pointing to the incriminated source code is very helpful for the maintainer._ --> ### PoC <!-- _Complete instructions, including specific configuration details, to reproduce the vulnerability._ --> First do a fresh install of SvelteKit 2 with the example app. Typescript. 1. `npm run build` 2. `npm run preview` 3. Go to http://localhost:4173 (works) 4. curl -X GET -d "{}" http://localhost:4173/bye 5. Application crashes and http://localhost:4173 is down ### Impact <!-- _What kind of vulnerability is it? Who is impacted?_ --> Denial of Service for apps using `adapter-node`
