Overview
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling due to an improper check of complex JSON in the HTTP handler. An attacker can cause excessive memory and CPU consumption by submitting specially-crafted payloads that meet the default request size limit, potentially leading to timeouts in the auditing subroutine and rendering the server unresponsive.
