Technical details
The vulnerability is a missing authorization check (CWE-862) in the Update controller (controllers/update.php), specifically the index() method. The Update class does not implement any authorization interface, causing the framework to treat all actions as public. An attacker can send a simple HTTP GET request to /index.php?controller=update&action=index to trigger SQL ALTER TABLE statements and delete the runtime cache directory as the web server user. No authentication or user interaction is required; the attack is entirely remote and unauthenticated. The exploit is publicly available and the issue was reported early but remains unpatched.
