CVE-2023-46298: Next.js missing cache-control header may lead to CDN caching empty reply

October 22, 2023 (updated October 28, 2023)

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.
