WowOptin: Next-Gen Popup Maker – Create Stunning Popups and Optins for Lead Generation <= 1.4.24 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Installation

The WowOptin: Next-Gen Popup Maker – Create Stunning Popups and Optins for Lead Generation plugin for WordPress is vulnerable to unauthorized arbitrary plugin installation due to a missing capability check on the 'install_and_active_plugin' function in all versions up to, and including, 1.4.24. This makes it possible for authenticated attackers, with Subscriber-level access and above, to install and activate arbitrary plugins.
