"The version of Jenkins running on the remote web server is prior to 2.245 or is a version of Jenkins LTS prior to 
2.235.2. It is, therefore, affected by multiple stored cross-site scripting (XSS) vulnerabilities in various components 
including its build time trend page, build cause page, tooltips & build console page. This is due to improper 
validation of user-supplied input before returning it to users. An authenticated, remote attacker can exploit this, by 
convincing a user to click a specially crafted URL, to execute arbitrary script code in a user's browser session.

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