Summary

Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to a denial of service via Excessive Allocation (CAPEC-130). An authenticated user can submit a specially crafted request to affected Entity Analytics endpoints containing an oversized input value that causes excessive resource consumption, which may render Kibana unavailable.
