 "title": "Blocksy Companion <= 2.1.58 - Authenticated (Contributor+) Sensitive Information Exposure via blocksy_posts Shortcode",
 "description": "The Blocksy Companion plugin for WordPress is vulnerable to Sensitive Information Exposure via the blocksy_posts shortcode and posts block in all versions up to, and including, 2.1.58. This is due to the plugin accepting arbitrary post types, including non-viewable ones, and allowing filtering by protected meta keys and values supplied in shortcode attributes. This makes it possible for authenticated attackers with Contributor-level access and above to list content from non-public post types and infer protected post meta values.",
