CVE-2026-94483

HIGH 8.3

Published 2026-10-02 · Last modified 2026-10-06

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.

ELEVATED IMPACT

    • workaround: Audit and restrict the `images.remotePatterns` configuration in `next.config.js` to eliminate untrusted hostnames, or remove the `remotePatterns` configuration entirely if external image fetching is not required. Additionally, egress network filtering can be enforced to prevent application containers or hosts from reaching private network ranges. Caveats: Disabling or removing remote image entries will prevent external image optimization.
