Technical details

The vulnerability is an Insecure Direct Object Reference (IDOR) in the REST API endpoints, specifically in the 'context' parameter of user-type dynamic content blocks. The plugin fails to validate user input on this parameter, allowing an attacker to directly reference and retrieve arbitrary user objects. Exploitation requires a published page using a Kirki template with at least one user-type dynamic content block, and user IDs are enumerable via standard WordPress REST endpoints.
