CVE-2022-2187Public exploitNetwork attack vector

Reflected XSS via unescaped request URI

Published Jul 17, 2022 · Updated Aug 3, 2024

Reflected XSS in Contact Form 7 Captcha before 0.1.2 allows remote attackers to execute script via a crafted admin-page URL. The cf7sr_adminhtml settings renderer writes $_SERVER['REQUEST_URI'] directly into the form action attribute without escaping it. A logged-in administrator must open the crafted link in an old browser, bounding the impact to script execution in that administrator's WordPress session.
