"The version of Kibana installed on the remote host is prior to 8.19.10, 9.1.10, or 9.2.4. It is, therefore, affected 
by a vulnerability as referenced in the ESA_2026_03 advisory.

  - An allocation of resources without limits or throttling vulnerability in Kibana Fleet leads to excessive resource 
    allocation via a specially crafted request. This causes the application to perform redundant processing operations 
    that continuously consume system resources until service degradation or complete unavailability occurs. This 
    affects Kibana versions 7.10.0 to 7.17.29, 8.0.0 to 8.19.9, 9.0.0 to 9.1.9, and 9.2.0 to 9.2.3. (CVE-2026-0530)

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