CVE-2026-94483: Vercel Next.js

Medium severity, CVSS 6.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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.

Affected products

• Vercel Next.js: from 16.0.0, before 16.3.8 (fixed in 16.3.8)
