Vrs-hCk has discovered a vulnerability in the ionFiles component for
Joomla!, which can be exploited by malicious people to disclose
sensitive information.

Input passed to the "file" parameter in download.php (when "download"
is set to "1") is not properly sanitised before being used. This can
be exploited to download arbitrary files via directory traversal
attacks.

The vulnerability is confirmed in version 4.4.2. Other versions may
also be affected.
