## Description

The WebberZone Top 10 plugin for WordPress is vulnerable to Sensitive Information Exposure via the 'thumb_meta' attribute of the [tptn_list] shortcode in all versions up to, and including, 4.6.1, due to the plugin accepting any meta key, protected keys included, as the thumbnail meta field and printing the stored value as the image source of each listed post. This makes it possible for authenticated attackers, with contributor-level access and above, to expose URL-formatted values of protected post meta from posts shown in the popular posts list.
