Summary
Next.js Allows a Denial of Service (DoS) with Server Actions
Details

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.
