Kibana 9.2.x / 9.3.x < 9.4.0 Missing Authorization (ESA-2026-191)

medium Nessus Plugin ID 364502

Synopsis

The remote host is affected by a missing authorization vulnerability.

Description

The version of Kibana installed on the remote host is 9.2.0 through 9.3.8 inclusive. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-191 advisory.

- Missing Authorization (CWE-862) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An internal API surface within the Metrics Experience feature did not enforce a Kibana-level authorization check that an equivalent, related API in the same feature did enforce. As a result, a user who held only data-store-level read access to an index, but no corresponding Kibana feature privilege, could retrieve index-derived metric data through Kibana that the properly-authorized API would otherwise have blocked. (CVE-2026-102410)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Kibana version 9.4.0 or later. Note that there is no patched release within the 9.2.x or 9.3.x lines.
