## Technical details

An unauthenticated SQL injection vulnerability exists in User/cancel.php and User/cancel_t.php where the ID parameter from GET requests is concatenated directly into DELETE SQL queries without escaping or parameterized binding. The vulnerable code performs no session or authentication checks, allowing any remote attacker to manipulate the ID parameter with SQL syntax (e.g., OR 1=1) to delete arbitrary or all records from the order_list or t_order tables. The vulnerability is publicly exploitable and could potentially be escalated to remote code execution via OUTFILE operations.
