"The version of Jenkins Enterprise or Jenkins Operations Center running on the remote web server is 2.303.x prior to
2.303.30.0.4, or 2.x prior to 2.319.2.9. It is, therefore, affected by a remote code execution vulnerability in the
Kubernetes Client API. An authenticated, local attacker can exploit this, by entering YAML that would be processed by
the Kubernetes Client API.

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