Description
The Kirki - Freeform Page Builder, Website Builder & Customizer plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 6.3.2 via the 'context' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to expose arbitrary users' sensitive profile data (including email address, display name, nicename, registration date, profile image URL, and any string-valued user meta fields such as first name, last name, nickname, description, and custom meta keys) via the REST response. Exploitation requires a published page that uses a Kirki template containing at least one user-type dynamic content block; target user IDs are enumerable via standard WordPress REST endpoints, making the only prerequisite the presence of such a template on the site.
