The Listeo Core plugin for WordPress is vulnerable to unauthenticated arbitrary media upload in all versions up to, and including, 2.0.27 via the "listeo_core_handle_dropped_media" function. This is due to missing authorization and capability checks on the AJAX endpoint handling file uploads. This makes it possible for unauthenticated attackers to upload arbitrary media to the site's media library, without achieving direct code execution.
