CVE-2026-30694Public exploitNetwork attack vector

Remote code execution via file-manager filter bypass

Published Mar 19, 2026 · Updated Mar 19, 2026

Code injection in DedeCMS 5.7.118 and earlier allows remote attackers to execute arbitrary PHP code through the file manager. The file_manage_control.php blacklist misspells array_filter and matches direct calls but not a quoted system callback, allowing crafted PHP to be written into a web-accessible file. Network access is sufficient under the published assessment; loading the resulting web shell runs commands with the web server process's privileges.
