Input validation vulnerability in Responsive YouTube Video Gallery Plugin for WordPress – YouTube Showcase 3.5.1

The YouTube Showcase plugin for WordPress has a security issue in versions up to 3.5.1. This means that someone who doesn’t have permission to access the website can use a specific method to add their own code. There is no known way for them to do this, but if there is another plugin or theme installed on the website, they could potentially cause harm by deleting files, getting private information, or running their own code.
