CVE-2024-47831
Denial of Service condition in Next.js image optimization
Impact
### 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. #### Credits Brandon Dahler (brandondahler), AWS Dimitrios Vlastaras
