CVE-2026-2184Public exploitNetwork attack vector

Unauthenticated command execution via unescaped archive filename

Published Feb 8, 2026 · Updated Feb 8, 2026

OS command injection in Great Developers Certificate Generation System allows remote attackers to execute commands via a crafted archive filename. In restructured/csv.php, the upload handler passes the untrusted photo filename directly to exec() when invoking tar or unzip, without shell escaping or validation. No authentication is required, and successful exploitation runs arbitrary commands with the web server account's privileges.
