 "title": "User Profile Builder <= 4.0.3 - Unauthenticated Stored Cross-Site Scripting via Signup Details on Unconfirmed Emails List",
 "description": "The User Profile Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via registration signup details in all versions up to, and including, 4.0.3 due to signup meta being built into an HTML string passed to jQuery inside an inline onclick handler on the Users with Unconfirmed Email list, where stored character references are decoded back into live markup. This makes it possible for unauthenticated attackers to inject arbitrary web scripts that execute when an administrator views a pending signup's details. Exploitation requires Email Confirmation to be enabled and an administrator to open the signup meta dialog.",
