Why these techniques?

SQL injection via unsanitized 'id' parameter enables arbitrary database queries by editors+, facilitating system owner/user discovery (T1033), local group/role discovery (T1069.001), local account discovery (T1087.001), and data collection from the WordPress database (T1213.006). CSRF lack amplifies via tricked logged-in users.
