CVE-2026-40073
CVE-2026-40073 · SvelteKit has a BODY_SIZE_LIMIT bypass in @sveltejs/adapter-node
This page contains facts from public vulnerability sources. Check the original advisory before updating.
SvelteKit is a framework for rapidly developing robust, performant web applications using Svelte. Prior to 2.57.1, under certain circumstances, requests could bypass the BODY_SIZE_LIMIT on SvelteKit applications running with adapter-node. This bypass does not affect body size limits at other layers of the application stack, so limits enforced in the WAF, gateway, or at the platform level are unaffected. This vulnerability is fixed in 2.57.1.
