Does this matter?
Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.
Description
SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.20.6 , unsanitized search param names cause XSS vulnerability. You are affected if you iterate over all entries of event.url.searchParams inside a server load function.
