Official description
The Contact Form to DB by BestWebSoft – Messages Database Plugin For WordPress plugin for WordPress is vulnerable to Stored Cross-Site Scripting via cntctfrm_contact_dropdown Parameter in all versions up to, and including, 1.7.5 due to insufficient input sanitization and output escaping.
