"According to its its self-reported version number, the version of Jenkins running on the remote web server is Jenkins
LTS prior to 2.277.3 or Jenkins weekly prior to 2.286. It is, therefore, affected by a vulnerability:

  - In Eclipse Jetty 7.2.2 to 9.4.38, 10.0.0.alpha0 to 10.0.1, and 11.0.0.alpha0 to 11.0.1, CPU usage can
