AC-3 Access Enforcement partial match
prevent

Enforces access-control checks on /admin/adminHome.php so that unauthenticated remote users cannot reach the vulnerable code path at all.

SI-2 Flaw Remediation partial match
prevent

Mandates timely remediation of the publicly disclosed SQL-injection flaw in the Online Art Gallery Shop application.
