CVE-2026-2226Public exploitNetwork attack vector

Authenticated RCE via unsafe ZIP extraction

Published Feb 9, 2026 · Updated Feb 9, 2026

Remote code execution in DouPHP 1.9 and earlier allows remote authenticated users to execute PHP code through a crafted ZIP import. The backup import path joins the user-controlled sql_filename value to data/backup and passes the resulting archive to file_unzip with the web root as the extraction target. Administrator access is required; a crafted archive uploaded through admin/file.php can place a PHP web shell in the web root and grant command execution as the web-server account.
