Summary
The WP-Members Membership Plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL Query String in all versions up to, and including, 3.5.6 due to insufficient input sanitization and output escaping. This allows unauthenticated attackers to inject arbitrary web scripts that execute if they can trick a user into clicking a link. Exploitation requires the victim to first visit the attacker-crafted URL and then click the Terms of Service link on the registration page.
Risk Assessment
An attacker could execute arbitrary JavaScript in the victim's browser, potentially leading to session theft or other actions in the user's context.
Recommendation
Update the WP-Members plugin to a version newer than 3.5.6 once available.

Original NVD description (English source)
The WP-Members Membership Plugin plugin for WordPress is vulnerable to Reflected Cross-Site Scripting via URL Query String in all versions up to, and including, 3.5.6 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that execute if they can successfully trick a user into performing an action such as clicking on a link. Successful exploitation requires the victim to first visit the attacker-crafted URL and then click the Terms of Service link rendered on the resulting registration page.
