Next.js missing cache-control header may lead to CDN caching empty reply

ALTO 7.5CVE-2023-46298 · GHSA-c59h-r6p8-q9wc · Published 22/10/2023 · updated 17/06/2026

Package	Affected versions	Patched versions
next.js vercel	`= 13.4.20< 13.4.20`	`13.4.20`
next npm	`≥ 0.9.9, < 13.4.20-canary.13`	`13.4.20-canary.13`

Description

Next.js before 13.4.20-canary.13 lacks a cache-control header and thus empty prefetch responses may sometimes be cached by a CDN, causing a denial of service to all users requesting the same URL via that CDN. Cloudflare considers these requests cacheable assets.
