Description
The Ninja Countdown | Fastest Countdown Builder plugin for WordPress is vulnerable to unauthorized loss of data due to a missing capability check on the 'ninja_countdown_admin_ajax' AJAX endpoint in all versions up to, and including, 1.5.0. This makes it possible for authenticated attackers, with Subscriber-level access and above, to delete arbitrary countdowns.
