Security Advisories 🚨

🚨 Next.js authorization bypass vulnerability

Impact

If a Next.js application is performing authorization in middleware based on pathname, it was possible for this authorization to be bypassed for pages directly under the application's root directory. For example:

• [Not affected] https://example.com/
• [Affected] https://example.com/foo
• [Not affected] https://example.com/foo/bar

Patches

This issue was patched in Next.js 14.2.15 and later.

If your Next.js application is hosted on Vercel, this vulnerability has been automatically mitigated, regardless of Next.js version.

Workarounds

There are no official workarounds for this vulnerability.

🚨 Denial of Service condition in Next.js image optimization

Impact

The image optimization feature of Next.js contained a vulnerability which allowed for a potential Denial of Service (DoS) condition which could lead to excessive CPU consumption.

Not affected:

• The next.config.js file is configured with images.unoptimized set to true or images.loader set to a non-default value.
• The Next.js application is hosted on Vercel.

Patches

This issue was fully patched in Next.js 14.2.7. We recommend that users upgrade to at least this version.

Workarounds

Ensure that the next.config.js file has either images.unoptimized, images.loader or images.loaderFile assigned.

🚨 Next.js Cache Poisoning

Impact

By sending a crafted HTTP request, it is possible to poison the cache of a non-dynamic server-side rendered route in the pages router (this does not affect the app router). When this crafted request is sent it could coerce Next.js to cache a route that is meant to not be cached and send a Cache-Control: s-maxage=1, stale-while-revalidate header which some upstream CDNs may cache as well.

To be potentially affected all of the following must apply:

• Next.js between 13.5.1 and 14.2.9
• Using pages router
• Using non-dynamic server-side rendered routes e.g. pages/dashboard.tsx not pages/blog/[slug].tsx

The below configurations are unaffected:

• Deployments using only app router
• Deployments on Vercel are not affected

Patches

This vulnerability was resolved in Next.js v13.5.7, v14.2.10, and later. We recommend upgrading regardless of whether you can reproduce the issue or not.

Workarounds

There are no official or recommended workarounds for this issue, we recommend that users patch to a safe version.

🚨 Next.js Denial of Service (DoS) condition

Impact

A Denial of Service (DoS) condition was identified in Next.js. Exploitation of the bug can trigger a crash, affecting the availability of the server.

This vulnerability can affect all Next.js deployments on the affected versions.

Patches

This vulnerability was resolved in Next.js 13.5 and later. We recommend that users upgrade to a safe version.

Workarounds

There are no official workarounds for this vulnerability.

🚨 Next.js Server-Side Request Forgery in Server Actions

Impact

A Server-Side Request Forgery (SSRF) vulnerability was identified in Next.js Server Actions by security researchers at Assetnote. If the Host header is modified, and the below conditions are also met, an attacker may be able to make requests that appear to be originating from the Next.js application server itself.

Prerequisites

• Next.js (<14.1.1) is running in a self-hosted* manner.
• The Next.js application makes use of Server Actions.
• The Server Action performs a redirect to a relative path which starts with a /.

* Many hosting providers (including Vercel) route requests based on the Host header, so we do not believe that this vulnerability affects any Next.js applications where routing is done in this manner.

Patches

This vulnerability was patched in #62561 and fixed in Next.js 14.1.1.

Workarounds

There are no official workarounds for this vulnerability. We recommend upgrading to Next.js 14.1.1.

Vercel and the Next.js team thank Assetnote for responsibly disclosing this issue to us, and for working with us to verify the fix. Thanks to:

🚨 Next.js Vulnerable to HTTP Request Smuggling

Impact

Inconsistent interpretation of a crafted HTTP request meant that requests are treated as both a single request, and two separate requests by Next.js, leading to desynchronized responses. This led to a response queue poisoning vulnerability in the affected Next.js versions.

For a request to be exploitable, the affected route also had to be making use of the rewrites feature in Next.js.

Patches

The vulnerability is resolved in Next.js 13.5.1 and newer. This includes Next.js 14.x.

Workarounds

There are no official workarounds for this vulnerability. We recommend that you upgrade to a safe version.

🚨 Next.js missing cache-control header may lead to CDN caching empty reply

Next.js before 13.4.20-canary.13 lacks a cache-control header and thus empty prefetch responses may sometimes be cached by a CDN, causing a denial of service to all users requesting the same URL via that CDN. Cloudflare considers these requests cacheable assets.

🚨 Unexpected server crash in Next.js

Impact

When specific requests are made to the Next.js server it can cause an unhandledRejection in the server which can crash the process to exit in specific Node.js versions with strict unhandledRejection handling.

• Affected: All of the following must be true to be affected by this CVE

  • Node.js version above v15.0.0 being used with strict unhandledRejection exiting
  • Next.js version v12.2.3
  • Using next start or a custom server

• Not affected: Deployments on Vercel (vercel.com) are not affected along with similar environments where next-server isn't being shared across requests.

🚨 Improper CSP in Image Optimization API for Next.js versions between 10.0.0 and 12.1.0

Next.js is a React framework. Starting with version 10.0.0 and prior to version 12.1.0, Next.js is vulnerable to User Interface (UI) Misrepresentation of Critical Information. In order to be affected, the next.config.js file must have an images.domains array assigned and the image host assigned in images.domains must allow user-provided SVG. If the next.config.js file has images.loader assigned to something other than default, the instance is not affected. Version 12.1.0 contains a patch for this issue. As a workaround, change next.config.js to use a different loader configuration other than the default.

Impact

• Affected: All of the following must be true to be affected
  • Next.js between version 10.0.0 and 12.0.10
  • The next.config.js file has images.domains array assigned
  • The image host assigned in images.domains allows user-provided SVG
• Not affected: The next.config.js file has images.loader assigned to something other than default

Patches

Next.js 12.1.0

Workarounds

Change next.config.js to use a different loader configuration other than the default, for example:

module.exports = {
  images: {
    loader: 'imgix',
    path: 'https://example.com/myaccount/',
  },
}

Or if you want to use the loader prop on the component, you can use custom:

module.exports = {
  images: {
    loader: 'custom',
  },
}

🚨 Denial of Service Vulnerability in next.js

Impact

Vulnerable code could allow a bad actor to trigger a denial of service attack for anyone running a Next.js app at version >= 12.0.0, and using i18n functionality.

• Affected: All of the following must be true to be affected by this CVE
  • Next.js versions above v12.0.0
  • Using next start or a custom server
  • Using the built-in i18n support
• Not affected:
  • Deployments on Vercel (vercel.com) are not affected along with similar environments where invalid requests are filtered before reaching Next.js.

Patches

A patch has been released, [email protected], that mitigates this issue. We recommend all affected users upgrade as soon as possible.

Workarounds

We recommend upgrading whether you can reproduce or not although you can ensure /${locale}/_next/ is blocked from reaching the Next.js instance until you upgrade.

🚨 Unexpected server crash in Next.js.

Next.js is a React framework. In versions of Next.js prior to 12.0.5 or 11.1.3, invalid or malformed URLs could lead to a server crash. In order to be affected by this issue, the deployment must use Next.js versions above 11.1.0 and below 12.0.5, Node.js above 15.0.0, and next start or a custom server. Deployments on Vercel are not affected, along with similar environments where invalid requests are filtered before reaching Next.js. Versions 12.0.5 and 11.1.3 contain patches for this issue. Note that prior version 0.9.9 package next hosted a different utility (0.4.1 being the latest version of that codebase), and this advisory does not apply to those versions.
