Technical details
The plugin fails to implement proper authorization checks in its REST API endpoints, allowing authenticated users with author-level access or higher to query and read metadata of private and draft posts belonging to other authors. The vulnerability is in the REST API functionality that does not validate whether the requesting user owns or has permission to access the queried posts. This is an authorization bypass that requires existing authenticated access to the WordPress site with minimum author privileges.
