Detailsinfo

A vulnerability was found in vercel next.js up to 16.1.4. It has been declared as problematic. Affected by this vulnerability is an unknown functionality of the file /_next/image of the component Image Optimization Endpoint. The manipulation with an unknown input leads to a denial of service vulnerability. The CWE definition for the vulnerability is CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. As an impact it is known to affect availability. The summary by CVE is:

A denial of service vulnerability exists in self-hosted Next.js applications that have `remotePatterns` configured for the Image Optimizer. The image optimization endpoint (`/_next/image`) loads external images entirely into memory without enforcing a maximum size limit, allowing an attacker to cause out-of-memory conditions by requesting optimization of arbitrarily large images. This vulnerability requires that `remotePatterns` is configured to allow image optimization from external domains and that the attacker can serve or control a large image on an allowed domain. Strongly consider upgrading to 15.5.10 or 16.1.5 to reduce risk and prevent availability issues in Next applications.

The advisory is shared at github.com. This vulnerability is known as CVE-2025-59471 since 09/16/2025. The exploitation appears to be difficult. The attack can be launched remotely.
