Reflected XSS via unescaped active-tab parameter
Published Mar 13, 2024 · Updated Apr 8, 2026
Reflected XSS in Contact Form 7 5.9 and earlier allows remote attackers to execute scripts in a user's browser through a crafted active-tab value. In admin/edit-contact-form.php, the attacker-controlled value was emitted into a hidden input attribute without sufficient output escaping. Execution requires a WordPress user with access to the Contact Form 7 editor to follow the crafted link, after which the script runs under the site's origin.
