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.
The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
