Input validation vulnerability in Popliup – WordPress Popup Plugin 1.1.1

The Popliup – WordPress Popup Plugin for WordPress has a security issue that affects all versions up to 1.1.1. This vulnerability allows attackers with Subscriber-level access or higher to include and run files on the server. This means they can run any PHP code in those files, which could let them bypass security measures, access private information, or execute code. This can be particularly dangerous if the plugin allows users to upload images or other types of files that are usually considered safe.
