Advisory
Source description from Wordfence Intelligence.
The Calendar Event Multi View plugin for WordPress is vulnerable to authorization bypass due to a missing capability check on event creation and deletion in versions up to, and including, 1.4.06 . This makes it possible for unauthenticated attackers to manipulate events. Additionally, some of the event fields do not undergo proper sanitization leading to the potential of Stored Cross-Site Scripting.
