The Countdown, Coming Soon, Maintenance – Countdown & Clock plugin for WordPress is vulnerable to unauthorized access due to a missing capability check on the conditionsRow and switchCountdown functions in all versions up to, and including, 2.7.8. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject PHP Objects and modify the status of countdowns.
