Synopsis

The remote host is affected by a cross-site request forgery vulnerability.

Description

The version of Kibana installed on the remote host is 8.19.x prior to 8.19.20, or 9.x prior to 9.4.5. It is, therefore, affected by a vulnerability as referenced in the ESA-2026-99 advisory.

- Cross-Site Request Forgery (CWE-352) in Kibana can lead to privilege escalation via Cross Site Request Forgery (CAPEC-62). A user who is permitted to create visualizations can save a specially crafted Vega visualization that, when it is opened by another user, causes authenticated requests to be issued to Kibana in the context of the viewing user's session. (CVE-2026-72658)

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 8.19.20, 9.4.5 or later.
