Kibana 9.4.x < 9.4.5 Missing Authorization (ESA-2026-147)

medium Nessus Plugin ID 344320

Synopsis

The remote host is affected by a missing authorization vulnerability.

Description

The version of Kibana installed on the remote host is 9.4.x prior to 9.4.5. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-147 advisory.

- Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Privilege Abuse (CAPEC-122). An authorization control was not applied to a Kibana Entity Store configuration operation, allowing an authenticated user with elevated Kibana privileges to indirectly cause a background task to read from Elasticsearch indices that user is not authorized to access. Derived entity data from those indices is then exposed through the entity store output. (CVE-2026-78601)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update to Kibana version 9.4.5 or later.
