CVE-2026-102427 is an unrestricted dangerous-file-upload vulnerability in OrdaSoft Joomla CCK versions earlier than 8.3.16. The component's site/uploader.php handler is reachable through the normal frontend task=getContent route without authentication or access-control checks. Although uploaded content is subjected to magic-byte MIME validation, the extension allowlist is commented out and the saved extension is derived directly from the attacker-controlled filename. An attacker can upload an image/PHP polyglot with a .php extension to a web-accessible location under the Joomla web root, where the PHP handler executes the appended PHP payload.

An unauthenticated remote code execution vulnerability in OrdaSoft Joomla CCK versions earlier than 8.3.16. An unauthenticated attacker can access the uploader through frontend routing and upload an image/PHP polyglot with an attacker-selected .php extension. Because extension allow-list enforcement is commented out and the file is saved beneath the Joomla web root, the uploaded PHP can be executed by the server.
A critical unauthenticated remote code execution vulnerability in OrdaSoft Joomla CCK versions before 8.3.16. The uploader's extension allow-list was commented out, allowing an image/PHP polyglot to pass MIME validation and be saved as an executable PHP file under the Joomla web root.
