The Post Grid Master plugin for WordPress has a security issue that can be exploited by hackers. This is because the plugin does not properly clean up the information it receives from users before displaying it, making it vulnerable to a type of attack called Reflected Cross-Site Scripting. This means that attackers can insert harmful code into web pages, which can be triggered if a user clicks on a link. This vulnerability affects all versions of the plugin up to and including 3.4.13.
