Unauthenticated Cross Site Scripting (XSS) in Royal Elementor Addons Pro < 1.7.1041 versions.

AnalysisAI

Unauthenticated reflected/stored cross-site scripting in Royal Elementor Addons Pro WordPress plugin versions prior to 1.7.1041 allows remote attackers to inject arbitrary JavaScript that executes in a victim's browser when they interact with a crafted link or page. No public exploit identified at time of analysis, but the unauthenticated nature combined with the popularity of Elementor-ecosystem plugins makes this a credible threat to WordPress sites running the Pro variant. Patchstack disclosure indicates a fixed version is available.

Technical ContextAI

Royal Elementor Addons Pro (CPE: cpe:2.3:a:royal_elementor_addons:royal_elementor_addons_pro) is a commercial premium add-on suite for the Elementor page builder on WordPress, providing widgets, templates, and dynamic content modules. The flaw maps to CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-controlled input is rendered into HTML/JavaScript context without adequate encoding or sanitization. In WordPress plugin ecosystems, such issues typically arise in widget shortcode attributes, AJAX endpoints, or query-parameter-driven rendering paths that reflect attacker data into the DOM.

RemediationAI

Vendor-released patch: upgrade Royal Elementor Addons Pro to version 1.7.1041 or later via the WordPress plugin update mechanism or by downloading the latest build from the vendor account portal, per the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/wpr-addons-pro/vulnerability/wordpress-royal-elementor-addons-pro-plugin-1-7-1041-cross-site-scripting-xss-vulnerability. If immediate patching is not possible, deploy a WAF rule (Patchstack, Wordfence, or equivalent) to filter script-injection patterns against the plugin's endpoints and shortcode parameters; restrict editor/admin sessions to a hardened browser profile to limit damage from successful payload execution; and consider temporarily deactivating the Pro plugin on internet-exposed sites if it is not actively in use, accepting the trade-off of losing Royal-specific widgets and templates until the update is applied.
