Overview
kibana is an open source (Apache Licensed), browser-based analytics and search dashboard for Elasticsearch.
Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via the connector reporting operation. An attacker can exhaust system resources by submitting an oversized query expression, causing the process to become unresponsive and preventing legitimate users from accessing the service until it is restarted. This is only exploitable if an authenticated user with at least read-only privileges submits a specially crafted request.
