CVE-2024-5212Network attack vector

Reflected XSS via unescaped envato_code input

Published Aug 31, 2024 · Updated Apr 8, 2026

Reflected XSS in tagDiv Composer 5.0 and earlier allows remote attackers to inject scripts through the envato_code[] parameter. The on_ajax_register_forum_user function uses the parameter without sufficient input sanitization or output escaping. Execution requires a user to follow a crafted link, after which the script runs in that user's browser context.
