SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to versions 2.70.4 and 3.1.1, the reroute hook could rewrite an invalid percent-encoded pathname into a valid route and reach a comparison that decoded the original malformed pathname outside the guarded decoding operation. The resulting unhandled URIError could crash an adapter-node server and deny service to other requests. This issue is fixed in 2.70.4 and 3.1.1.
