"The version of the Elastic Kibana instance on the remote host is 8.x prior to 8.11.1. It is, therefore, affected
by an information disclosure vulnerability. In the event of an infrequent error returned from an Elasticsearch cluster,
in cases where there is user interaction and an unhealthy cluster, sensitive information may be recorded in Kibana logs
within the error message. The error message may contain account credentials for the kibana_system 67 user, API Keys, and
credentials of Kibana end-users.  

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