NewCVE-2025-6087 (opens in a new tab)How to fix?
Upgrade @opennextjs/cloudflare to version 1.3.0 or higher.
Overview
@opennextjs/cloudflare is a Cloudflare builder for next apps
Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) via the /_next/image endpoint. An attacker can retrieve arbitrary remote content and potentially expose internal services or facilitate phishing attacks by crafting requests that proxy external resources through the victim's domain. This is only exploitable if unauthenticated access to the /_next/image endpoint is permitted.
Workaround
This vulnerability can be mitigated by configuring the remotePatterns filter in the Next.js configuration to allow-list only trusted external image URLs.
