The Paid Memberships Pro – Content Restriction, User Registration, & Paid Subscriptions plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Readonly User Field via [pmpro_member_profile_edit] Shortcode in all versions up to, and including, 3.8.1 due to insufficient input sanitization and output escaping.
