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.
