Input validation vulnerability in WP Image Uploader 1.0.1

The WP Image Uploader plugin for WordPress has a security issue that can be exploited by hackers. This vulnerability affects all versions up to 1.0.1. The problem lies in a function called gky_image_uploader_main_function() which does not properly check for authorization. This means that attackers who are not logged in can delete any file they want if they can trick the site administrator into clicking on a link.
