Kibana 9.4.x < 9.4.6 / 9.5.x < 9.5.1 Incorrect Authorization (ESA-2026-122)

medium Nessus Plugin ID 344311

Synopsis

The remote host is affected by an incorrect authorization vulnerability.

Description

The version of Kibana installed on the remote host is 9.4.x prior to 9.4.6, or 9.5.x prior to 9.5.1. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-122 advisory.

- Incorrect Authorization (CWE-863) in Kibana can lead to unauthorized modification of data via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user holding only Security Solution read access in a Kibana space could enumerate and change the state of Entity Store maintainer tasks, silently disabling Entity Analytics maintenance for that space. (CVE-2026-72641)

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, 9.5.1 or later.
