"The version of Kibana installed on the remote host is 9.3.x prior to 9.3.8 or 9.4.x prior to 9.4.4. It is,
therefore, affected by multiple vulnerabilities as referenced in the ESA-2026-65 and ESA-2026-67 advisories.

  - Missing Authorization (CWE-862) in Kibana allows an authenticated user to access and modify Cloud Connect
    configuration and service settings without the required feature privileges, via direct requests to
    insufficiently protected product endpoints. (CVE-2026-63141)

  - Missing Authorization (CWE-862) in Kibana can lead to unauthorized information disclosure via Privilege
    Abuse (CAPEC-122). A user with limited feature privileges can access workflow execution outputs in their
    Kibana space without the authorization required to do so through the documented API. The accessible data
    may include sensitive information returned by workflow steps, such as results from connected data sources
    that the caller would not otherwise be authorized to access. (CVE-2026-63143)

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