AI-Generated

The vulnerability affects Next.js versions 15.5.0 to 15.5.20 and 16.0.0 to 16.2.10, specifically when using the default image loader with the Image Optimization API configured to optimize remotely hosted images. Maliciously crafted images can lead to CPU exhaustion on the /_next/image endpoints, potentially impacting application performance. Developers and organizations utilizing these versions of Next.js with the default image loader should prioritize upgrading to versions 15.5.21 or 16.2.11 to mitigate this risk.

Original NVD Description

Next.js is a React framework for building full-stack web applications. In versions 15.5.0 through 15.5.20 and 16.0.0 through 16.2.10, when self-hosting Next.js with the default image loader, the Image Optimization API can optimize remotely hosted images if configured (not enabled by default). If those images contain malicious content, they can cause CPU exhaustion in /_next/image endpoints.Only config.images.remotePatterns is affected, and just the patterns in that array, whereas config.images.unoptimized: true, config.images.loader: 'custom', and Vercel are not impacted. This issue has been fixed in versions 15.5.21 and 16.2.11.
