CVE-2025-8280Public exploitNetwork attack vector

Reflected XSS via unescaped request URI

Published Sep 12, 2025 · Updated Sep 12, 2025

Reflected XSS in Contact Form 7 reCAPTCHA 1.2.0 and earlier allows remote attackers to execute script in an administrator's browser. The settings-page renderer writes the unescaped REQUEST_URI server value into an HTML attribute, so a crafted admin.php query closes the attribute and injects script. Exploitation requires an authenticated administrator to open the crafted wp-admin URL in an old browser; execution is limited to that browser session.
