Kibana 9.1.x < 9.4.6 / 9.5.x < 9.5.2 Incorrect Authorization (ESA-2026-130)

medium Nessus Plugin ID 344324

Synopsis

The remote host is affected by an incorrect authorization vulnerability.

Description

The version of Kibana installed on the remote host is 9.1.x prior to 9.4.6, or 9.5.x prior to 9.5.2. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-130 advisory.

- Incorrect Authorization (CWE-863) in Kibana Entity Analytics can lead to a loss of security monitoring via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only read-level Security feature access, and no Elasticsearch privileges, could stop the recurring Privilege Monitoring engine task for a Kibana space. Privileged user monitoring then stops producing data for that space while the engine continues to report a healthy state to operators. (CVE-2026-72633)

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 9.4.6, 9.5.2 or later.
