What the vulnerability does
01Description
The Community Events plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the ajax_admin_event_approval() function in all versions up to, and including, 1.5.6. This makes it possible for unauthenticated attackers to approve arbitrary events via the 'eventlist' parameter.
