CVE-2023-6525Network attack vector

Stored XSS via unescaped progress bar attributes

Published Mar 16, 2024 · Updated Apr 8, 2026

Stored XSS in Roxnor ElementsKit Elementor Addons 3.0.3 and earlier allows remote authenticated users to inject scripts via progress bars. The progressbar.php renderer places attacker-controlled Elementor progress-bar attributes into page markup without sufficient input sanitization or output escaping. Editor access is required, and the script runs when a visitor opens the injected page, primarily on multisite sites or sites with unfiltered_html disabled.
