 "title": "WP Popular Posts <= 7.4.3 - Unauthenticated Sensitive Information Exposure via 'post_type' Parameter of the Widget REST Endpoint",
 "description": "The WP Popular Posts plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'post_type' parameter of the /wordpress-popular-posts/v2/widget REST API endpoint in all versions up to, and including, 7.4.3. This is due to the endpoint passing request parameters to the popular posts query without checking them against the public post types. This makes it possible for unauthenticated attackers to list published entries of non-public post types that have views or comments, and to read their titles, links and, through the excerpt option, their content.",
