 "title": "MDTF – Meta Data and Taxonomies Filter <= 1.3.9 - Authenticated (Contributor+) Sensitive Information Exposure via mdf_value Shortcode",
 "description": "The MDTF – Meta Data and Taxonomies Filter plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'mdf_value' shortcode in all versions up to, and including, 1.3.9, due to the shortcode returning the meta value of any post ID and meta key without checking whether the current user may read that post or whether the key is protected. This makes it possible for authenticated attackers, with Contributor-level access and above, to read meta of private and draft posts, including protected internal meta keys.",
