Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content <= 4.17.4 - Authenticated (Subscriber+) Sensitive Information Exposure via Shortcode Injection via Nickname and Biographical Info Profile Fields

  • Disclosed: 02.10.2026
  • Updated: 11.10.2026 10:22

The Paid Membership Plugin, Ecommerce, User Registration Form, Login Form, User Profile & Restrict Content – ProfilePress plugin for WordPress is vulnerable to Sensitive Information Exposure in all versions up to, and including, 4.17.4 via the get_user_profile_structure. This makes it possible for authenticated attackers, with subscriber-level access and above, to extract other users' email addresses, login names, and registration dates via the Member Directory's per-row user rebinding when attacker-controlled base64 payloads in the [pp-custom-html] shortcode invoke [profile-email], [profile-username], and [profile-date-registered]. When the WordPress users_can_register option is enabled, unauthenticated attackers can also exploit this vulnerability by supplying the split shortcode fragments through the plugin's own registration handler, which processes the reg_nickname and reg_bio fields without a nonce requirement.
