Input validation vulnerability in WP-BibTeX 3.0.1

The plugin called WP-BibTeX, which is used on WordPress websites, has a security issue called Cross-Site Request Forgery. This affects all versions of the plugin up to 3.0.1. The problem is that the plugin does not properly check for a security code when certain actions are performed, making it possible for someone without proper authorization to insert harmful code onto the website. This could happen if they are able to trick the website administrator into clicking on a link.
