Denial of Service condition in Next.js image optimization

✓ GitHub Reviewed MODERATE Has CVE

Advisory Details

### 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.
