Cross-Site Request Forgery Vulnerability in Sky Addons for Elementor

Summary

The Sky Addons for Elementor (Free Templates Library, Live Copy, Animations, Post Grid, Post Carousel, Particles, Sliders, Chart, Blog, Video Gallery) plugin for WordPress is vulnerable to Cross-Site Request Forgery in all versions up to, and including, 2.6.1. This is due to missing or incorrect nonce validation on the save_options() function. This makes it possible for unauthenticated attackers to update arbitrary options on the WordPress site via a forged request granted they can trick a site administrator into performing an action such as clicking on a link. Please note this is limited to option values that can be saved as arrays.
