# Impact :
***********
* WordPress 4.5 Research Korea Themes is prone to a vulnerability that lets attackers download arbitrary files because the application

fails to sufficiently sanitize user-supplied input. An attacker can exploit this issue to download arbitrary files within the context of the

web server process and obtain potentially sensitive informations. * An information exposure is the intentional or unintentional disclosure

of information to an actor that is not explicitly authorized to have access to that information. * The software has Relative Path Traversal

vulnerability and it uses external input to construct a pathname that should be within a restricted directory, but it does not

properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
