The Konnichiwa! Membership WordPress plugin is vulnerable to Reflected Cross-Site Scripting via the plan_id parameter in the ~/views/subscriptions.html.php file which allows attackers to inject arbitrary web scripts, in versions up to and including 0.8.3.
Solution:
The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users.
