Technical details
The vulnerability stems from loose inequality comparison (!=) of session user_type values in the User_Controller's authorization check, which is vulnerable to PHP type juggling (e.g., true != 1 evaluates to false). This affects configurations with non-standard session backends that return unexpected scalar types. The fix switches to strict comparison (!==) with proper type casting to prevent type coercion attacks. Authentication/authorization bypass requires exploitation of the session comparison logic during request handling.
