[counterintuitive] AI security review is uniformly effective across vulnerability classes

Use AI for detecting injection vulnerabilities \(SQL injection, XSS, command injection\) where it excels due to abundant training examples. Always have humans review authorization logic, access control, and business rule enforcement—these require understanding of who should access what, which is domain-specific and not reliably captured in training data.

Journey Context:
AI security review has a very uneven profile across vulnerability classes. For injection vulnerabilities—SQL injection, XSS, command injection—the model has seen millions of examples in training data and can detect these with high reliability, often better than junior security reviewers. But for authorization bugs—broken access control, privilege escalation, business logic violations—the model fails because these require understanding domain-specific rules about who should access what. OWASP ranks Broken Access Control as the number one web application security risk, but this is exactly where AI is weakest. The model can tell you that a SQL query is vulnerable to injection but cannot tell you that a regular user should not access admin endpoints because it does not understand the business rules. This creates a dangerous asymmetry: teams that rely on AI security review catch the easy bugs \(injection\) while missing the most critical ones \(authorization\), giving a false sense of security coverage. The fix is to map vulnerability classes to reviewer capabilities: AI for pattern-based vulnerabilities, humans for domain-logic vulnerabilities.
