Input validation vulnerability in Microblog Poster – Auto Publish on Social Media 2.1.6

The Microblog Poster – Auto Publish on Social Media plugin for WordPress has a security vulnerability that affects all versions up to and including 2.1.6. This is because it does not properly check for a special code that helps prevent unauthorized changes. This means that someone who is not logged in can change the plugin’s settings and add harmful code to a website, as long as they can trick the website owner into doing something, like clicking on a fake link.
