 "title": "ProfilePress – Paid Membership, Online Courses (LMS), Ecommerce, User Registration & Login Form, User Profile & Restrict Content <= 4.18.0 - Unauthenticated Privilege Escalation via Melange Form Registration Role",
 "description": "The Paid Membership, Online Courses (LMS), Ecommerce, User Registration & Login Form, User Profile & Restrict Content plugin for WordPress is vulnerable to Privilege Escalation via melange form registration in all versions up to, and including, 4.18.0. This is due to the plugin validating a submitted role, and falling back to a builder-assigned role, using the registration form that shares the melange form's ID instead of the melange form itself. This makes it possible for unauthenticated attackers to register with a role permitted by, or assigned by, an unrelated (possibly unpublished) registration form, which may be a privileged role such as Editor, depending on how that form is configured.",
