[counterintuitive] AI is superior at security vulnerability detection because it has been trained on all known CVEs

Use AI to catch known vulnerability patterns \(injection, XSS\) as a supplement to SAST tools; require human security review for logic flaws, race conditions, and authorization issues; treat AI security review as pattern matching, not security auditing

Journey Context:
AI models detect known vulnerability patterns well—they're essentially flexible static analysis tools that can identify SQL injection, XSS, and common misconfigurations. But they fail on vulnerability classes requiring understanding of intent and context: business logic flaws, TOCTOU race conditions, authorization boundary violations, and cryptographic misuse that appears syntactically correct. Research found that AI models frequently identify non-vulnerable code as vulnerable \(false positives from pattern over-matching\) while missing genuinely vulnerable code that doesn't match training patterns \(false negatives on novel combinations\). The distribution shift is fundamental: AI was trained on known vulnerabilities, so novel combinations are out-of-distribution. The most dangerous vulnerabilities—logic flaws that lead to data breaches—are precisely the ones AI is worst at finding because they require understanding what the code is supposed to do, not just what it does.
