Ultimate Addons for Elementor < 1.30.0 - Contributor+ Stored XSS

The “Ultimate Addons for Elementor” WordPress Plugin before 1.30.0 has several widgets that are vulnerable to stored Cross-Site Scripting (XSS) by lower-privileged users such as contributors, all via a similar method.

These vulnerabilities were discovered and patched by Brainstorm Force after the Wordfence Threat Intelligence team notified them of similar vulnerabilities in their " Elementor – Header, Footer & Blocks Template" plugin, and are nearly identical to the vulnerabilities we have recently disclosed in the main Elementor plugin: https://www.wordfence.com/blog/2021/03/cross-site-scripting-vulnerabilities-in-elementor-impact-over-7-million-sites/
