Kibana 8.12.x < 8.19.19 / 9.0.x < 9.3.8 / 9.4.x < 9.4.4 Multiple Vulnerabilities (ESA-2026-102 / ESA-2026-108)
medium Nessus Plugin ID 338738
Synopsis
The remote host is affected by multiple vulnerabilities.Description
The version of Kibana installed on the remote host is 8.12.x prior to 8.19.19, 9.0.x prior to 9.3.8, or 9.4.x prior to 9.4.4. It is, therefore, affected by multiple vulnerabilities as referenced in the ESA-2026-102 and ESA-2026-108 advisories.- Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal Kibana data retrieval capability used by Elastic Defend endpoint response actions did not enforce the Security Solution and endpoint privileges that its user-facing equivalents require, and it retrieved data with elevated internal permissions rather than the permissions of the requesting user. As a result, an authenticated low-privileged Kibana user with no Security Solution privileges, endpoint privileges and no Elasticsearch privileges on the underlying data, could read endpoint response action records and the corresponding response content returned by managed hosts. (CVE-2026-72661)
- Allocation of Resources Without Limits or Throttling (CWE-770) in Kibana can lead to denial of service via Excessive Allocation (CAPEC-130). An authenticated user who is authorized to manage maintenance windows could submit a specially crafted, malformed payload that causes the Kibana process to consume excessive resources. Kibana becomes unresponsive for all users and does not recover without manual intervention.
(CVE-2026-72653)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
