Input validation vulnerability in Easy Social Like Box – Popup – Sidebar Widget 4.0

The Easy Social Like Box – Popup – Sidebar Widget plugin for WordPress has a security issue where it can be attacked by malicious code through a certain part of the plugin’s code. This can happen in all versions up to and including 4.0 because the code does not properly protect against harmful input. This means that someone with a certain level of access to the plugin can insert harmful code into a page that will run whenever someone visits that page.
