Successful SQL injection could expose sensitive user data or allow unauthorized access. The
get_user_by_idfunction inws.php(lines 22-37) directly uses thelookup_userGET parameter without sanitization, which causes unsanitized data to be passed directly into a SQL query. An attacker could manipulate this parameter to inject arbitrary SQL code, potentially extracting user credentials or modifying application data.
