"The version of Elastic APM Server installed on the remote host is 8.x prior to 8.16.1. It is, therefore, affected by 
an information disclosure vulnerability:

    - APM server logs could contain parts of the document body from a partially failed bulk index request. 
      Depending on the nature of the document, this could disclose sensitive information in APM Server 
      error logs. (CVE-2024-11994)

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