Input validation vulnerability in Custom Block Builder – Lazy Blocks 3.8.2

The Custom Block Builder – Lazy Blocks plugin for WordPress has a security issue that can be exploited by hackers. This issue, known as Reflected Cross-Site Scripting, affects all versions up to 3.8.2. It happens because the plugin does not properly clean input and output, which allows attackers to add harmful code to web pages. This can happen if a user is tricked into clicking on a link.
