CVE-2024-2821Public exploitNetwork attack vector

Friend-link modification via unchecked id request

Published Mar 22, 2024 · Updated Aug 27, 2025

Cross-site request forgery in DedeCMS 5.7 allows remote attackers to modify a friend-link entry through an administrator's browser. The friendlink_edit.php handler accepts an attacker-selected id in a forged request without verifying that the authenticated user intentionally submitted it. Exploitation requires user interaction and an authenticated administrative session, and the documented consequence is limited to changing the selected friend-link record.
