Description

Impact

The image optimization feature of Next.js contained a vulnerability which allowed for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption.

Not affected:

  • The next.config.js file is configured with images.unoptimized set to true or images.loader set to a non-default value.
  • The Next.js application is hosted on Vercel.

Patches

This issue was fully patched in Next.js 14.2.7. We recommend that users upgrade to at least this version.

Workarounds

Ensure that the next.config.js file has either images.unoptimized, images.loader or images.loaderFile assigned.
