Next.js Content Injection Vulnerability for Image Optimization

A vulnerability in **Next.js Image Optimization** has been fixed in **v15.4.5** and **v14.2.31**. The issue allowed attacker-controlled external image sources to trigger file downloads with arbitrary content and filenames under specific configurations. This behavior could be abused for phishing or malicious file delivery. All users relying on `images.domains` or `images.remotePatterns` are encouraged to upgrade and verify that external image sources are strictly validated.
