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.js14.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
<14.1.1
) is running in a self-hosted* manner./
.* 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
.Credit
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:
next.config.js
file is configured withimages.unoptimized
set totrue
orimages.loader
set to a non-default value.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 eitherimages.unoptimized
,images.loader
orimages.loaderFile
assigned.Credits

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.
Credit
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.
Credits
Thanks to the PackDraw team for responsibly disclosing 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
15.2.3
14.2.25
13.5.9
12.3.5
Note: Next.js deployments hosted on Vercel are automatically protected against this vulnerability.
Workaround
If patching to a safe version is infeasible, it is recommend that you prevent external user requests which contain the
x-middleware-subrequest
header from reaching your Next.js application.Credits
CVE-2025-32421
Summary
We received a responsible disclosure from Allam Rachid (zhero) for a low-severity race-condition vulnerability in Next.js. This issue only affects the Pages Router under certain misconfigurations, causing normal endpoints to serve
pageProps
data instead of standard HTML.Learn more here
