3.9.13. It is, therefore, affected by multiple vulnerabilities.

  - An issue was discovered in Joomla! before 3.9.13. A
    missing token check in com_template causes a CSRF
    vulnerability. (CVE-2019-18650)

  - An issue was discovered in Joomla! before 3.9.13. A
    missing access check in the phputf8 mapping files could
    lead to a path disclosure. (CVE-2019-18674)

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