What it is

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. Attackers can exploit it by crafting a malicious URL and getting a user to click a link with said URL. This vulnerability is fixed in 2.20.6.
