Affected versions are: Before 8.5.5, and from 8.6.0 before 8.8.1 of Atlassian Jira Server and Data Center allow remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the XML export view.

According to its self-reported version number, the instance of Atlassian Jira hosted on the remote web server is prior to 7.13.16, 8.0.0 prior to 8.5.5 or 8.6.0 prior to 8.8.1. It is, therefore, affected by a vulnerability which permits remote attackers to inject arbitrary HTML or JavaScript via a cross site scripting (XSS) vulnerability in the XML export view.

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

According to its self-reported version number, the instance of Atlassian JIRA hosted on the remote web server is   6.x prior to 8.5.5 or 8.6.x prior to 8.8.1. It is, therefore, affected by a cross-site scripting (XSS) vulnerability   in its view issue screen 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 this issue but has instead relied only on the application's self-reported version   number.
