CVE-2026-40720Network attack vector

Stored script execution via unescaped page content

Published Jun 17, 2026 · Updated Jun 17, 2026

Stored cross-site scripting in Royal Elementor Addons Pro before 1.7.1041 allows remote attackers to inject scripts into site pages. The plugin stores attacker-controlled input without sufficient sanitization and later renders it without adequate output escaping; public sources identify no parameter, function, or file. No authentication is required to plant a payload, but a user must view an affected page before the script executes in the site's origin.
