Input validation vulnerability in mEintopf 0.2.1

The WordPress plugin called “mEintopf” has a security issue that makes it vulnerable to a type of attack called “Reflected Cross-Site Scripting.” This can happen in any version of the plugin, including the latest one, because it does not properly clean up the information that is entered and shown on the website. This allows hackers who are not logged in to add harmful code to the website, which can be triggered if a user clicks on a specific link.
