Input validation vulnerability in WordPress Bitcoin Payments – Blockonomics 3.3

The WordPress Bitcoin Payments – Blockonomics plugin can be vulnerable to a type of attack known as reflected Cross-Site Scripting. This attack can occur if an unauthenticated attacker can trick a user into clicking a link. If the plugin is an older version, such as one before 3.3, it can allow for attackers to inject malicious web scripts into pages that will execute when the user clicks the link.
