Technical details
The vulnerability is a stored cross-site scripting flaw in the WP Crowdfunding plugin caused by insufficient input sanitization and output escaping of the 'first_name' parameter. Authenticated attackers with subscriber-level access and above can inject arbitrary JavaScript code that persists in the database. The payload executes when any user (including administrators) accesses the injected user profile via the ?show_user_id= parameter, enabling cross-privilege script execution within the admin's session. This affects all versions up to and including 2.2.1. A patch or update is required to properly sanitize and escape the affected parameter.
