CVE-2024-46982

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.

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-2024-51479

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.

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.
