Description
The CP Multi View Events Calendar plugin for WordPress is vulnerable to unauthorized modification and loss of data via the cp_multiviewadd_calendar, cp_multiviewdelete_calendar and cp_multiviewsaveautodel AJAX actions in all versions up to, and including, 1.4.41, due to a missing capability check on these functions, which rely only on a nonce that is shown to any user who can open the post editor. This makes it possible for authenticated attackers, with Contributor-level access and above, to create, modify and delete calendar views and to change the old-event auto-deletion settings of any calendar, which deletes past events.
