cross-site scripting (XSS) vulnerabilities :

  - A cross-site scripting (XSS) vulnerability exists when
    saving configuration revisions due to improper
    validation of user-supplied input to comments before
    returning it to users. An authenticated, remote attacker
    can exploit this, via a specially crafted request, to
    execute arbitrary script code in a user's browser
    session. (CVE-2017-7734)

  - A cross-site scripting (XSS) vulnerability exists when
    creating or editing user groups due to improper
    validation of user-supplied input to groups before
    returning it to users. An authenticated, remote attacker
    can exploit this, via a specially crafted request, to
    execute arbitrary script code in a user's browser
