CVE-2026-94544 · Severity: medium · CVSS 4.2 · Published 2026-10-02

Next.js is a web framework that allows developers to build full-stack web applications with features like Draft Mode for editors to preview unpublished content. A cache contamination vulnerability in versions 16.3.0 through 16.3.7 can cause unpublished draft content to leak to regular site visitors, or conversely allow published content to appear in draft previews. If a cached page is served with contaminated draft content, that content persists in the generated page and will be visible to all subsequent visitors until the cache is manually revalidated.

Technologies: [next (npm)](https://junglewise.ai/threats/technologies/npm-next), [Vercel Next.js](https://junglewise.ai/threats/technologies/next-js). Vendors: [npm](https://junglewise.ai/threats/vendors/npm), [Vercel](https://junglewise.ai/threats/vendors/vercel).

## How to fix

- next (npm): upgrade to 16.3.8 or later

  ```sh
  npm install next@16.3.8
  ```


## Technical details

The vulnerability occurs in the use cache deduplication mechanism, which shares pending cache fills for identical keys across concurrent requests without distinguishing Draft Mode requests from regular requests. An overlapping regular request can receive draft-dependent content, and if that request prerendered a page, the contaminated content persists in the static output. The issue affects deployments with Cache Components or experimental.useCache enabled that return draft-dependent cached content.
