CVE-2023-46298

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.

CVE-2024-34350

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.

CVE-2024-34351

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:

CVE-2024-47831

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.

CVE-2024-39693

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.

CVE-2024-51479

Impact

If a Next.js application is performing authorization in middleware based on pathname, it was possible for this authorization to be bypassed.

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.

We'd like to thank tyage (GMO CyberSecurity by IERAE) for responsible disclosure of this issue.

CVE-2024-56332

Impact

A Denial of Service (DoS) attack allows attackers to construct requests that leaves requests to Server Actions hanging until the hosting provider cancels the function execution.

Note: Next.js server is idle during that time and only keeps the connection open. CPU and memory footprint are low during that time.

Deployments without any protection against long running Server Action invocations are especially vulnerable. Hosting providers like Vercel or Netlify set a default maximum duration on function execution to reduce the risk of excessive billing.

This is the same issue as if the incoming HTTP request has an invalid Content-Length header or never closes. If the host has no other mitigations to those then this vulnerability is novel.

This vulnerability affects only Next.js deployments using Server Actions.

Patches

This vulnerability was resolved in Next.js 14.2.21, 15.1.2, and 13.5.8. We recommend that users upgrade to a safe version.

Workarounds

There are no official workarounds for this vulnerability.

CVE-2025-29927

Impact

It is possible to bypass authorization checks within a Next.js application, if the authorization check occurs in middleware.

Patches

  • For Next.js 15.x, this issue is fixed in 15.2.3
  • For Next.js 14.x, this issue is fixed in 14.2.25
  • For Next.js 13.x, this issue is fixed in 13.5.9
  • For Next.js 12.x, this issue is fixed in 12.3.5
  • For Next.js 11.x, consult the below workaround.

Note: Next.js deployments hosted on Vercel are automatically protected against this vulnerability.

Workaround

If patching to a safe version is infeasible, we recommend that you prevent external user requests which contain the x-middleware-subrequest header from reaching your Next.js application.

CVE-2025-48068

Summary

A low-severity vulnerability in Next.js has been fixed in version 15.2.2. This issue may have allowed limited source code exposure when the dev server was running with the App Router enabled. The vulnerability only affects local development environments and requires the user to visit a malicious webpage while npm run dev is active.

Because the mitigation is potentially a breaking change for some development setups, to opt-in to the fix, you must configure allowedDevOrigins in your next config after upgrading to a patched version. Learn more.

CVE-2025-57752

A vulnerability in Next.js Image Optimization has been fixed in v15.4.5 and v14.2.31. When images returned from API routes vary based on request headers (such as Cookie or Authorization), these responses could be incorrectly cached and served to unauthorized users due to a cache key confusion bug.

All users are encouraged to upgrade if they use API routes to serve images that depend on request headers and have image optimization enabled.

More details at Vercel Changelog

CVE-2025-55173

A vulnerability in Next.js Image Optimization has been fixed in v15.4.5 and v14.2.31. The issue allowed attacker-controlled external image sources to trigger file downloads with arbitrary content and filenames under specific configurations. This behavior could be abused for phishing or malicious file delivery.

All users relying on images.domains or images.remotePatterns are encouraged to upgrade and verify that external image sources are strictly validated.

More details at Vercel Changelog

CVE-2025-57822

A vulnerability in Next.js Middleware has been fixed in v14.2.32 and v15.4.7. The issue occurred when request headers were directly passed into NextResponse.next(). In self-hosted applications, this could allow Server-Side Request Forgery (SSRF) if certain sensitive headers from the incoming request were reflected back into the response.

All users implementing custom middleware logic in self-hosted environments are strongly encouraged to upgrade and verify correct usage of the next() function.

GHSA-mwv6-3258-q52c

A vulnerability affects certain React packages for versions 19.0.0, 19.0.1, 19.1.0, 19.1.1, 19.1.2, 19.2.0, and 19.2.1 and frameworks that use the affected packages, including Next.js 15.x and 16.x using the App Router. The issue is tracked upstream as CVE-2025-55184.

A malicious HTTP request can be crafted and sent to any App Router endpoint that, when deserialized, can cause the server process to hang and consume CPU. This can result in denial of service in unpatched environments.

GHSA-5j59-xgg2-r9c4

It was found that the fix addressing CVE-2025-55184 in React Server Components was incomplete and did not fully prevent denial-of-service attacks in all payload types. This affects React package versions 19.0.2, 19.1.3, and 19.2.2 and frameworks that use the affected packages, including Next.js 13.x, 14.x, 15.x and 16.x using the App Router. The issue is tracked upstream as CVE-2025-67779.

A malicious HTTP request can be crafted and sent to any Server Function endpoint that, when deserialized, can enter an infinite loop within the React Server Components runtime. This can cause the server process to hang and consume CPU, resulting in denial of service in unpatched environments.
