The Nelio Content – Editorial Calendar & Social Media Auto-Posting plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 4.5.0 This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to permanently delete any reusable social message (nc_reusable_social post), including those authored by administrators or other privileged users.
