WP Crowdfunding permits subscriber scripts to run in an administrator's session
WP Crowdfunding through 2.2.1 inadequately sanitizes and escapes first_name. A Subscriber or higher-privileged user can save script content that runs when the profile is rendered. An administrator viewing a user's profile through show_user_id can trigger the stored payload in the administrator's browser session.

Technical description
The WP Crowdfunding plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'first_name' parameter in all versions up to, and including, 2.2.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. An administrator viewing any user's profile via the ?show_user_id= parameter will render the attacker's stored payload in the admin's browser session, enabling cross-privilege script execution.
