CVE-2025-2806Network attack vector

Reflected XSS via unescaped data parameter

Published May 8, 2025 · Updated Apr 8, 2026

Reflected XSS in tagDiv Composer 5.3 and earlier allows remote attackers to inject scripts through the data parameter. The legacy/common/wp_booster/td_ajax.php handler reflects the data value into a response without sufficient sanitization and output escaping. Unauthenticated delivery is possible, but execution requires a user to follow a crafted link and occurs in that user’s browser under the affected site’s origin.
