A.8.27 mandates security-by-design principles (least privilege, default-deny, distrust-external-input, hardening, design review against attack patterns) that reach path-traversal neutralization in many but not all cases; business-process-specific controls, outsourced development, and residual design choices leave a bounded remainder unaddressed.
