The remote host is affected by a denial of service vulnerability.

Description

The version of Kibana installed on the remote host is 8.x prior to 8.19.19, or 9.0.x prior to 9.3.5. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-48 advisory.

- 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 that causes excessive resource consumption, which may render Kibana unavailable. (CVE-2026-72652)
