OWASP A06:2025 — Insecure Design

What This Skill Does

Guides detection, analysis, and remediation of Insecure Design vulnerabilities — architecture-level failures where security controls are absent or structurally inadequate. Unlike implementation bugs, insecure design cannot be fixed by patching code alone; it requires redesigning the flow or adding missing control layers.
