Here is an example that triggers it: /admin/app/user/?q=first_name+%3D+%22First%22+and+last_name+%3D+%22Last%22&o=-12.-11.3
The specific rule being triggered is: AWS#AWSManagedRulesSQLiRuleSet#SQLi_QUERYARGUMENTS
While it is possible to disable the rule for the admin panel, it is not acceptable in a compliant environment.
