Overview
next is a react framework.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the Partial Prerendering resume endpoint when unauthenticated POST requests with the Next-Resume: 1 header are processed and attacker-controlled postponed state data is handled. An attacker can cause the server process to crash and exhaust system memory by sending large or highly compressed payloads that are buffered or decompressed without size limits.
Note:
This is only exploitable if the application is running with experimental.ppr: true or cacheComponents: true configured along with the NEXT_PRIVATE_MINIMAL_MODE=1 environment variable.
