"According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior
to 7.3.16, or is 8.x < 8.5.7, or 8.6.x < 8.12.0. It is, therefore, affected by an information disclosure vulnerability.
An unauthenticated, remote attacker can exploit this, via the /ViewUserHover.jspa endpoint, in order to enumerate users.

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