 "title": "Kirki – Freeform Page Builder, Website Builder & Customizer <= 6.3.2 - Unauthenticated Insecure Direct Object Reference to Sensitive Information Exposure via Collection Rendering 'context' Parameter",
 "description": "The Kirki plugin for WordPress is vulnerable to Insecure Direct Object Reference via the 'context' parameter of the frontend collection REST endpoint (kirki/v1/frontend/collection) in all versions up to, and including, 6.3.2. The permission check validates only the context 'type' and 'id', but the whole user-supplied context array is then merged into the render options, after the objects the check resolved. This makes it possible for unauthenticated attackers to send a context of a type that is allowed without restriction, such as 'term', carrying an extra 'user' key. That skips the list_users check for user contexts and renders a collection's user dynamic fields, such as email address, display name and user meta, for any user ID.",
