Improper Input Validation

CVE-2024-23641

Severity High
Score 7.5/10

Summary

SvelteKit is a web development kit. In SvelteKit 2, sending a GET request with a body eg `{}` to a built and previewed/hosted sveltekit app throws `Request with GET/HEAD method cannot have the body.` and crashes the preview/hosting. After this happens, one must manually restart the app. `TRACE` requests will also cause the app to crash. Prerendered pages and SvelteKit 1 apps are not affected. This issue affects @sveltejs/adapter-node versions 2.0.0 through 2.1.2, 3.0.0 through 3.0.3, and 4.0.0, and @sveltejs/kit versions 2.0.0 through 2.4.2.
