Summary

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.

Patch / fix

  • npm next 14.2.7
  • vercel next.js 14.2.7

Fencer Vulns keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.

The maintainers of vercel/next.js published their own advisory on GitHub. Reviewed sources take precedence over it.

CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
