CVE-2024-47831
Next.js image optimization has Denial of Service condition
Next.js is a React Framework for the Web. Cersions on the 10.x, 11.x, 12.x, 13.x, and 14.x branches before version 14.2.7 contain a vulnerability in the image optimization feature which allows for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption. Neither the next.config.js file that is configured with images.unoptimized set to true or images.loader set to a non-default value nor the Next.js application that is hosted on Vercel are affected. This issue was fully patched in Next.js 14.2.7. As a workaround, ensure that the next.config.js file has either images.unoptimized, images.loader or images.loaderFile assigned.
