Kibana 9.4.x < 9.4.4 Information Disclosure (ESA-2026-161)

medium Nessus Plugin ID 344313

Synopsis

The remote host is affected by an information disclosure 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-2026-161 advisory.

 - Observable Response Discrepancy (CWE-204) in the Kibana Osquery feature can lead to information disclosure via Query System for Information (CAPEC-54). An authenticated user holding Osquery live-query privileges could determine whether a scheduled query identifier exists in a Kibana space they are not authorized to access. (CVE-2026-78584)

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.
