CVE-2025-4257Public exploitNetwork attack vector

Browser script execution via unfiltered cstatus

Published May 5, 2025 · Updated May 8, 2025

Cross-site scripting in SeaCMS 13.2 allows remote authenticated users to inject script through cstatus in admin_pay.php. The handler processes the client-supplied cstatus value without strict filtering, allowing markup or script content to reach the generated page. Low-privileged access and victim interaction are required, bounding the consequence to browser-side integrity impact without direct service interruption.
