CVE-2026-94483 vercel CVE debrief

Who should care

Defenders responsible for Next.js applications using Image Optimization with allow-listed remote URLs should assess exposure and prioritize remediation. This includes operators, platform administrators, vulnerability management teams, and security teams who need to verify and audit allow-listed remote URLs in `images.remotePatterns` for hosts that may not be trusted with their DNS entries. They should also consider upgrading to version 16.3.8 or later, if

Why it matters

Defenders should prioritize verifying and remediating this vulnerability in their Next.js applications, especially those using Image Optimization with allow-listed remote URLs, to prevent potential SSRF attacks.
