Description
Impact
An attacker-controlled, allow-listed remote URL can lead to server-side request forgery (e.g. to private IPs) during Image Optimization.
Workaround
Audit allow-listed remote URLs in images.remotePatterns (see https://nextjs.org/docs/app/getting-started/images#remote-images) for hosts that may not be trusted with their DNS entries. If no images.remotePatterns are configured, your app is not affected.
NVD description
Next.js is a React framework for building full-stack web applications. From 16.0.0 until 16.3.8, Image Optimization can follow attacker-controlled DNS resolution for a remote URL that matches images.remotePatterns, allowing the optimized image fetch to reach private IP addresses after the URL passes the allow-list check. Applications without images.remotePatterns are not affected. Administrators unable to upgrade should audit allow-listed hosts and avoid entries whose DNS records are not trusted. This issue is fixed in version 16.3.8.
