Kibana 9.4.x < 9.4.4 Privilege Escalation (ESA-2026-83)

high Nessus Plugin ID 338737

Language:

Synopsis

The remote host is affected by a privilege escalation vulnerability.

Description

The version of Kibana installed on the remote host is 9.4.x prior to 9.4.4. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-83 advisory.

- Kibana Agent Builder does not correctly verify that the requesting user holds the privileges required by a separate Kibana feature before it creates and runs a tool that invokes that feature's functionality. This allows privilege escalation and could lead to disclosure of sensitive information that the user is not authorized to read. (CVE-2026-72681)

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 9.4.4 or later.
