Upgrade next to version 16.1.7, 16.2.0-canary.51 or higher.
Overview
next is a react framework.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to the unbounded postponed resume-body buffering behavior of the next-resume: 1 header. An attacker can cause excessive memory usage and disrupt service availability by sending oversized POST payloads with the next-resume header, which are buffered without consistent size enforcement in certain non-minimal deployments. This is only exploitable if the App Router with Partial Prerendering capability is enabled (via experimental.ppr or cacheComponents) and the deployment is not in minimal mode.
