To fix the problem, we need to ensure that user-provided data is safely embedded into SQL queries using placeholder parameters or prepared statements. Specifically, we should avoid directly concatenating user-provided keys into the query string. Instead, we can use a switch-case or if-else structure to handle different keys and construct the query string safely.
- Modify the
QueryCoursefunction indatabase/course.goto use a switch-case structure to handle different keys and construct the query string safely. - Ensure that the
QueuedQueryfunction indatabase/queue.gouses the constructed query string with placeholder parameters.
