Kibana 9.3.x < 9.4.3 Privilege Escalation (ESA-2026-61)

high Nessus Plugin ID 344319

Synopsis

The remote host is affected by a privilege escalation vulnerability.

Description

The version of Kibana installed on the remote host is 9.3.x prior to 9.4.3. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-61 advisory.

 - Incorrect Authorization (CWE-863) in Kibana can lead to privilege escalation via Exploiting Incorrectly Configured Access Control Security Levels (CAPEC-180). A user holding workflow edit permissions could cause scheduled workflow executions to run with the privileges of a different, higher-privileged user, allowing access to and modification of data beyond their own authorization scope. (CVE-2026-63137)

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 9.4.3 or later.
