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.
