CVE
CVE-2026-40073
@sveltejs/adapter-node has a BODY_SIZE_LIMIT bypass
Under certain circumstances, requests could bypass the BODYSIZELIMIT 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.
