What is CVE-2026-5428?

The Royal Elementor Addons plugin for WordPress contains a vulnerability that allows authenticated users with Author access or higher to exploit Stored Cross-Site Scripting. This occurs through insufficient output escaping in the rendering process of image captions within the Image Grid/Slider/Carousel widget. By utilizing the wp_kses_post() function instead of the more appropriate esc_attr(), attackers can inject malicious scripts into the media grid widgets. These scripts will execute whenever a user views a page featuring the compromised images, potentially leading to unauthorized access or data exposure.
