CVE-2026-0577Public exploitNetwork attack vector

Authenticated code execution via unchecked image upload

Published Jan 4, 2026 · Updated Jan 4, 2026

Unrestricted file upload in Code Projects Online Product Reservation System 1.0 allows remote authenticated users to execute PHP code. The product-image handler in /handgunner-administrator/prod.php passes the submitted temporary path and original filename to move_uploaded_file without checking its extension, MIME type, content, or filename. An authenticated administrator can place a PHP web shell in the web-accessible upload directory and invoke it remotely as the web server.
