Sina Extension for Elementor < 3.3.12 - Contributor+ Stored XSS
The “Sina Extension for Elementor” WordPress Plugin before 3.3.12 has several widgets that are vulnerable to stored Cross-Site Scripting (XSS) by lower-privileged users such as contributors, all via a similar method.
Additionally the following widgets appear to have similar vulnerabilities:
Sina Content Slider:title_tag,subtitle_tag parameters
Sina Particle Layer:title_tag parameter
Sina title:title_tag,subtitle_tag parameters
These vulnerabilities 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/
