The Next.js team recently disclosed CVE-2025-32421, a low-severity vulnerability allowing for CDN cache poisoning in some scenarios.

The engineering team at Netlify has confirmed that all Next.js sites on Netlify are not vulnerable. The vulnerability requires use of a CDN that may cache responses without explicit Cache-Control headers, but Netlify’s CDN never does so.

As a general security precaution, we recommend upgrading to the latest versions of the Next.js framework and allowing automatic updates of the OpenNext Netlify Next.js adapter.
