Summary

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.
