nextnpm

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.
Is GHSA-cjq9-62q9-8jv4 in any of your client repos?
Checking one package by hand is fine. Checking it across forty client projects is not. NPMscan reads the lockfiles in every GitHub repo you pick, finds each project with an affected next, and gives you the command that fixes it.
