CVE-2026-94483Network attack vectorHinoki check available

Private-IP request forgery via allow-listed DNS resolution

Published Oct 2, 2026 · Updated Oct 2, 2026

Server-side request forgery in Vercel Next.js 16.0.0 through 16.3.7 lets remote attackers reach private IPs via Image Optimization. The image optimizer accepts a remote URL matching images.remotePatterns but does not constrain the address to which its hostname resolves before fetching it. Exploitation requires an allow-listed host with attacker-controlled DNS; applications without images.remotePatterns are not affected.
