An issue was discovered in components/com_users/models/registration.php in Joomla! before 3.6.5.

An issue was discovered in templates/beez3/html/com_content/article/default.php in Joomla! before 3.6.5. Inadequate permissions checks in the Beez3 layout override of the com_content article view allow users to view articles that should not be publicly accessible, as demonstrated by an index.php?option=com_content&view=article&id=1&template=beez3 request.

The file scanning mechanism of JFilterInput::isFileSafe() in Joomla! CMS before 3.6.5 does not consider alternative PHP file extensions when checking uploaded files for PHP content, which enables a user to upload and execute files with the `.php6`, `.php7`, `.phtml`, and `.phpt` extensions. Additionally, JHelperMedia::canUpload() did not blacklist these file extensions as uploadable file types.

The register method in the UsersModelRegistration class in controllers/user.php in the Users component in Joomla! before 3.6.4, when registration has been disabled, allows remote attackers to create user accounts by leveraging failure to check the Allow User Registration configuration setting.
