CVE-2026-51078Public exploitNetwork attack vector

Authenticated command execution via blacklist bypass

Published Jul 27, 2026 · Updated Jul 27, 2026

Remote command execution in Dede CMS 5.7.118 and earlier allows remote authenticated users to run OS commands via file_manage_control.php. The save path reverses addslashes escaping with stripslashes, omits get_defined_functions from its blacklist, and writes restored str input into a PHP file. A valid backend file-manager session and CSRF token are required; requesting the saved file executes PHP system functions with web-server privileges.
