medium Nessus Plugin ID 330364

Language:

Synopsis

The remote host is affected by multiple vulnerabilities.

Description

The version of Kibana installed on the remote host is 9.4.x prior to 9.4.4. It is, therefore, affected by multiple vulnerabilities as referenced in the ESA-2026-70 and ESA-2026-73 advisories.

- Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via user-supplied identifiers that reference scheduled query result data from Kibana Spaces the requester is not authorized to access. (CVE-2026-63259)

- Missing Authorization (CWE-862) in Kibana can lead to unauthorized cross-space information disclosure via user-supplied input that circumvents space-level access control. (CVE-2026-63262)

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

Solution

Update to Kibana version 9.4.4 or later.
