Popup Maker WP 1.2.2.1 - 1.4.5 - Subscriber+ Zero-Argument PHP Callable Invocation via Missing Authorization

The Popup Maker WP WordPress plugin through 1.4.5 does not perform authorization checks on several of its actions and exposes its management page to any logged-in user, allowing users with a low-privileged role such as Subscriber to store display-targeting values that are later invoked as zero-argument PHP callables on public page loads, leading to sensitive information disclosure and denial of service.
