a vulnerability as referenced in the ESA-2024-25 advisory.

  - An allocation of resources without limits or throttling in Elasticsearch can lead to an OutOfMemoryError
    exception resulting in a crash via a specially crafted query using an SQL function. (CVE-2024-43709)

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